Add regex separators for split row/list/column (#8707)
# Description

Verified on discord with maintainer

Change adds regex separators in split rows/column/list. The primary
motivating reason was to make it easier to split on separators with
unbounded whitespace without requiring a lot of trim jiggery. But,
secondary motivation is the same as the set of all motivations for
adding split regex features to most languages.

# User-Facing Changes

Adds -r option to split rows/column/list.

# Tests + Formatting

Ran tests, however tests.nu fails with unrelated errors:

Upon investigating seeing this difference:

This seems unrelated to my changes, but can investigate further if
desired.
