Create subset for Austrailian and New Zealand soil semantics

[pbuttigieg]

Closes #1366

[cmungall]

I recommend following the existing naming conventions and using hyphen-separated lower case terms

I prefer acronyms to be spelled out, but I appreciate the spelled out name is quite long

I appreciate there is a precedent for the camelcase https://github.com/ANZSoilData/ANZSoilML so if it's important to mirror the source then ANZSoil is fine

[pbuttigieg]

Yes, we have an unruly mix. I want to retain the envo prefix so there's an indication that this is an adaptation of ANZSoil based on ENVO semantic approaches.

Otherwise some would mistake this for an official distribution from that authority.

Yes, it's in the full IRI, but not in the titles of the distributed files

envoANZSoil is OK by me

[pbuttigieg]

I've gotten informal approvals in the editors' Slack. I'll wait for at least one here.

Thx - Slack not normally open on my desktop - I'll go take a look.
