SPDX license list 3.29.0 rewrote every opensource.org seeAlso URL from
opensource.org/licenses/<ID> to opensource.org/license/<ID> (and e.g.
opensource.org/license/mit/ to opensource.org/license/MIT). Package metadata
in the wild (Maven POM <license><url>, npm, etc.) still uses the older forms,
so regenerating the list would stop LicenseByURL from resolving them.
Fall back to a normalized index of the opensource.org entries that ignores the
www. prefix, /licenses/ vs /license/, case, and a trailing slash. The index is
built from the generated urlToLicense map, so it works with both the current
and the updated license list without changes to the generator. URL forms that
would normalize to different licenses are left out rather than guessed.

Update the license_list.go to have more permissible inputs for greater SPDXID matching.
EX:
GPL3 gpl3 gpl-3 and GPL-3 can all map to GPL-3.0-only
By moving all strings to lower and removing the "-" we're able to return valid SPDX license ID for a greater diversity of input strings.
