let extensions specify geyser api version instead of base api version

[onebeastchris]

Relies on https://github.com/GeyserMC/api/pull/2

Changes:

• added geyserApiVersion() to Geyser API, which returns a ApiVersion class with a built in version compatibility check
• Extensions are checked against Geyser API version now to prevent crashes when trying to load extensions using newer api than is provided - to account for the old way, we check if the version is 1.0.0.

Bumping the base api version seems to have fixed building.

Needs rebase or merge
