* 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.

* Fix path when expanding tilde
Expanding tilde with no other relative paths would result in:
`$HOME/` instead of `$HOME`. This occurs when users run `cd` with
no extra arguments. In that case, the user's PWD would include the
trailing separator. This does not happen when explicitly passing
a value, such as `cd ~`, because in that case, the path would be
canonicalized.
This happens because std::path::PathBuf::push always adds a separator,
even if adding an empty path, which is what happens when `cd` is
invoked.

* Fix alias import
Alias importing was registering the alias id as a decl instead of alias.
This caused issues when hiding and then reimporting the alias.
