Sort by regular expression or lexicographically, find uniqes, shuffle, or evaluate rust selections without spawning a new command for each.

== Example
. Imagine you want to sort these stages
+
[source,groovy]
----
stage("Build") { # Step 1
8+3
}
stage("Compile") { # Step 5
math::log2(8)
}
stage("Assemble") { # Step 10
2^9+math::log2(10)
}
stage("Make") { # Step 100
not_a_formula
}
----
. Select the stage and stage body with: `%sstage<ret>MLM`
. Sort the selection by step number with: `:utils sort #\d+<ret>` (sort on whole capture) or `:utils sort "'.+?#(\d).+?'"` (sort on first capture group, which contains only the digits)
. Note if you just run `:utils sort<ret>`
== Configuration
[source,sh,title='sh']
----
cargo install --git https://github.com/austenadler/kakutils-rs
----
[source,title='kakrc']
----
define-command utils -params .. %{
eval -save-regs '"' %{
eval %sh{
# use kak_command_fifo kak_response_fifo;
kakutils-rs "$@"
}
}
}
----
== Usage
* Make multiple selections
* Run `utils sort` to sort the selections lexicographically
* Run `utils sort REGEX` to sort by regex match
** If the regex does not contain a capture group
** If the regex contains at least one capture group
== TODO
* I don't know what will happen with multiline strings and regex
* Figure out how to change the `no_skip_whitespace` option name in the source
* Get sort by selections working
