improve parsing of values with units (#9190 )

closes #9111 

# Description

this pr improves parsing of values with units (`filesizes`, `durations`
and any other **future values**) by:

1. allowing underscores in the value part
```nu
> 42kb          # okay
> 42_sec        # okay
> 1_000_000mib  # okay
> 69k_b         # not okay, underscores not allowed in the unit
```

2. improving error messages involving these values
```nu
> sleep 40-sec

# before
Error: nu::parser::parse_mismatch

  × Parse mismatch during operation.
   ╭─[entry #42:1:1]
 1 │ sleep 40-sec
   ·       ──┬──
   ·         ╰── expected duration with valid units
   ╰────

# now
Error:
  × duration value must be a number
   ╭─[entry #41:1:1]
 1 │ sleep 40-sec
   ·       ─┬─
   ·        ╰── not a number
   ╰────
```

3. unifying parsing of these values. now all of these use one function

# User-Facing Changes

filesizes and durations can now have underscores for readability

Nushell REPL

This directory contains the main Nushell REPL (read eval print loop) as part of the CLI portion of Nushell, which creates the nu binary itself.

Current versions of the nu binary will use the Nu argument parsing logic to parse the commandline arguments passed to nu, leaving the logic here to be a thin layer around what the core libraries.
