fix: use standard schema ending #

[henryiii]

Fixes #111. Added a test that ensures the old ones are still accepted.

This looks good. Thank you very much for taking the time to investigate that and provide the fix.

Just to clarify things, fastjsonschema does not need an exact match when using referenced schemas right? (i.e. the "parent" schema can be http://.../draft-07/schema# and the "referenced" schema can be https://.../draft-07/schema, right?)

I think so, but I'd have to set up a test to be sure. (Though I know you can't use https for 7 and below). I'd doubt it matters, though as fastjsonschema doesn't seem to care much about this value, you can literally set it to anything.

Thank you very much @HenryII.
I will think about a test in a follow up.
