* updated to reedline generic menus
* help menu with examples
* generic menus in the engine
* description menu template
* list of menus in config
* default value for menu
* menu from block
* generic menus examples
* change to reedline git path
* cargo fmt
* menu name typo
* remove commas from default file
* added error message
* Remove panic from BlockCommands run function
Instead of panicing, the run method now returns an error to prevent
nushell from unexpected termination.
* Add ability to open command to run with blocks
The open command tries to parse the content of the file
if there is a command called 'from (file ending)'. This works
fine if the command was 'built in' because the run method doesn't
fail in this case. It did fail on a BlockCommand, though.
This change will first probe if the command contains a block and
evaluate it, if this is the case. If there is no block, it will run
the command the same way as before.
* Add test open files with BlockCommands
* Update open.rs
* Adjust file type on open with BlockCommand parser

Enables the use of some features on reedline
- Keeping the line when clearing the screen with `Ctrl-L`
- Using the internal cut buffer between lines
- Submitting external commands via keybinding and keeping the line
Additional effect:
Keep the history around and do basic syncs (performance improvement
minimal as session changes have to be read and written)
Additional change:
Give the option to defer writing/rereading the history file to the
closing of the session ($config.sync_history_on_enter)

* Add streaming support to save for ExternalStream data
Prior to this change, save would collect data from an ExternalStream (data
originating from externals) consuming memory for the full amount of data piped
to it,
This change adds streaming support for ExternalStream allowing saving of
arbitrarily large files and bounding memory usage.
* Remove broken save test
This test passes but not for the right reasons, since this test was
written filename has become a required parameter. The parser outputs
an error but the test still passes as is checking the original un-mutated
file assuming save has re-written the contents.
This change removes the test.

* Add test for passing binary data through externals
This change adds an ignored test to confirm that binary data is passed
correctly between externals to be enabled in a later commit along with
the fix.
To assist in platform agnostic testing of binary data a couple of
additional testbins were added to allow testing on `Value::Binary` inside
`ExternalStream`.
* Support binary data to stdin of run-external
Prior to this change, any pipeline producing binary data (not detected
as string) then feed into an external would be ignored due to
run-external only supporting `Value::String` on stdin.
This change adds binary stdin support for externals allowing something
like this for example:
〉^cat /dev/urandom | ^head -c 1MiB | ^pv -b | ignore
1.00MiB
This would previously output `0.00 B [0.00 B/s]` due to the data not
being pushed to stdin at each stage.
Prior to this change, a pipeline of externals would result in high memory
usage if any of the producers in the chain, produced data faster than
the consumers.
For example a pipeline:
> fast-producer | slow-consumer
Would cause a build up of `Value::{String,Binary}`'s in the mpsc channels
between each command as values are added to the channels faster than they
are consumed, eventually OOM'ing depnding on system resources, the volume
of data and speed diff. between fast v's slow.
This change replaces the unbounded channels with bounded channels
to limit the number of values that can build up and providing
back-pressure to limit ram usage.
