StripCharsStart / String Layer

Remove specified characters from the beginning of strings. Similar to Python's str.lstrip() or Rust's trim_start_matches(). Removes any combination of specified characters until a non-matching character is found. Useful for:

Removing leading symbols (->text)
Cleaning numerical prefixes
Standardizing indented text
Processing formatted identifiers
