Feat: Add patterns for matching URLs and URL components

[PaulJPhilp]

This PR is much larger than I anticipated. Beside the addition of the URL patterns, I made the following changes:

1. added atoms.ts for basic building blocks. Changed the hex-color pattern to use the atoms.

2. changed toMatchString in test-utils to address issue [Bug]test-utils/ts-match-string doesn't work with trailing lookaheads. #81 . toMatchString now support 3 use cases:

   • match the exact string passed in
   • match any substring of the string passed in
   • match an exact substring of the string passed in

3. updated all the test cases to use the proposed change to the toMatchString API.

Please reach out to me if you have any questions.

Summary

This PR adds a URL matcher to the pattern library. The URL pattern can be used to match arbitrarily complex Web URLs as defined in this wikipedia article: based on the #RFC 1738 standard (https://datatracker.ietf.org/doc/html/rfc1738).

Besides the primary pattern url, this pattern also publishes regular expressions for the following URL subcomponents (see above article):

• urlScheme
• urlAuthority
• urlPath
• urlQuery
• urlFragment

as well as validation and finder helpers.

As well as the URL pattern, this PR adds a building blocks library called atoms (e.g. uppercase, lowercase, alphabetical, hexDigit). The hex-color pattern has been updated to use the atoms pattern library.

Test plan

There is a test suite for each URL subcomponent (scheme, authority, path, query, fragment) as well as the primary pattern: url.

As well, a test suite to test the patterns in the atoms collections.

Closed the pull request to separate out the proposed changes to to-match-string.ts. Ill break this into two PRs.
