build(deps): bump pyparsing from 3.0.1 to 3.0.3

[dependabot]

Bumps pyparsing from 3.0.1 to 3.0.3.

Release notes

Sourced from pyparsing's releases.

pyparsing 3.0.3

• Fixed regex typo in one_of fix for as_keyword=True.

• Fixed a whitespace-skipping bug, Issue #319, introduced as part of the revert of the LineStart changes. Reported by Marc-Alexandre Côté, thanks!

• Added header column labeling > 100 in with_line_numbers - some input lines are longer than others.

pyparsing 3.0.2

• Reverted change in behavior with LineStart and StringStart, which changed the interpretation of when and how LineStart and StringStart should match when a line starts with spaces. In 3.0.0, the xxxStart expressions were not really treated like expressions in their own right, but as modifiers to the following expression when used like LineStart() + expr, so that if there were whitespace on the line before expr (which would match in versions prior to 3.0.0), the match would fail.

  3.0.0 implemented this by automatically promoting LineStart() + expr to AtLineStart(expr), which broke existing parsers that did not expect expr to necessarily be right at the start of the line, but only be the first token found on the line. This was reported as a regression in Issue #317.

  In 3.0.2, pyparsing reverts to the previous behavior, but will retain the new AtLineStart and AtStringStart expression classes, so that parsers can chose whichever behavior applies in their specific instance. Specifically:

  # matches expr if it is the first token on the line (allows for leading whitespace)
  LineStart() + expr
  matches only if expr is found in column 1
  AtLineStart(expr)
  

• Performance enhancement to one_of to always generate an internal Regex, even if caseless or as_keyword args are given as True (unless explicitly disabled by passing use_regex=False).

• IndentedBlock class now works with recursive flag. By default, the results parsed by an IndentedBlock are grouped. This can be disabled by constructing the IndentedBlock with grouped=False.
