Add External Standards VLR #147

Issue description

There is currently no standard methodology for recording which LDP or other non standards the LAS file is meant to conform to.

Some possible standards that matter:

  1. LAS revision
  2. LAS Domain Profile (topobathy v1, topobathy v2, transmission lines, etc)
  3. ASPRS 2014
  4. ASPRS 2023 v1, v2, etc
  5. USGS LDP v____

Standardizing these with a lookup table would require constant maintenance. Perhaps the best solution would be for the VLR content to be a null-terminated array of URLs? Or maybe LAS wiki page names to err on the safe side?

I think an array that contained both a common (but not necessarily standardized) name and a URL would be good. Is there a common pattern for putting an array of strings in a VLR or EVLR?
