* Replace ansi-cut with ansi-str
There's no issues with it we just need to use it later.

* Include license text in all crates
Three crates already have license texts, so I'm keeping them, but
symlinking the `LICENSE` from the top level to the rest of the crate
directories. This works as long as `cargo publish` is done on a Unix-y
system and not Windows.
Also bump the copyright year to end in 2022.

For the width calculations for table layout the `strip_ansi` function
has to be called frequently. By checking for the ASCII control chars
(0x00 to 0x1f) except `\n` that are stripped by `strip_ansi_escapes` the number of
necessary allocations can be reduced significantly for the simple case
of text not containing ANSI escapes.
**Benchmark:**
```
nu -c "for i in 0..1000 { ls } | flatten | table"
```
**Allocation reduction**
Running on the nushell repo root as the directory, this change reduces the
allocation volume by approximately 400 MB
(Measured run via KDE heaptrack)
**Speed improvement to output**
Measured via `/usr/bin/time -v`

Ansi-cut expects ranges of character numbers (of the non-ansi control
sequence characters) instead of byte indices.
This fixes the panics when wrapping of non-unicode lines (which exceed
the demanded number of characters as byte indices).
Also rectifies some wrong wrapping of unicdoe containing lines that
don't panic
