feat: Remove 40 character limit on spell checking words

[Jason3S]

Adjust Base64 Detection

The Base64 detection pattern was preventing words longer than 40 characters from being spell checked. It has been turned off by default. To turn it back on add Base64 to ignoreRegExpList in CSpell settings.

A few new patterns were added by default to pick up many of the common cases that Base64 was designed for:

• Base64SingleLine - a stricter version Base64 detection that only matches single lines.
• Base64MultiLine - a stricter version Base64 detection that only matches multiple line Base64 strings.
• Hashes - detects common hash patterns:
  Example: sha1-tdRU3CGZriJWmfNGfloH87lVuv0=
  Supported prefixes:
  • sha1, sha256, sha512, md5, base64, crypt, bcrypt, scrypt, security-token, assertion

Minor Breakage

Because Base64 prevented anything longer than 40 characters from being checked, some misspellings might show up that were previously ignored.
