FontAwesome 6.2.0+ Support

[omacranger]

Adds support for FA 6.2.0+ (and their new confusing naming conventions)

• New font styles (sharp-solid, coming for other subsets [families?] in the future)
• Uses FontAwesome's new font family metadata file for checking available subsets for current & future font styles (if 6.2.0+)
• Adds / rearranges tests to check specific version / package functionality for better version / backwards compatibility coverage
• Adds ability to locate icons based on unicode value (if you're using those in CSS and can parse them out in bulk), or any of the various alias types
