Add support for Tiny Well-Known Binary format (TWKB)

Add support to read/write Geometries in Tiny Well-Known Binary format

Format specification: https://github.com/TWKB/Specification/blob/master/twkb.md
Examples at PostGIS: https://postgis.net/docs/ST_AsTWKB.html

This format reduce significantly the size of WKB geometries, could be useful managing big datasets with geometries.

Thanks

Hello! Thanks for opening this issue!

I agree this sounds like a great idea. I'll add it to my TODO list.
