v4.0.0: Upgrade H3 core to `v4` (#54)

First production release for H3 v4 🎉. As noted below, most function names have changed, but the H3 indexes have not, so while using v4 will require code changes it should be 100% backwards compatible with existing data. See the 4x migration guide for more information.

[4.0.0] - 2022-08-24

• ⚠️ Update h3 core library to v4.0.0. Almost all functions have been renamed to align with h3 core v4. Please take care when updating. You can see a list of changed function names in the core library documentation.
• ⚠️ The PostGIS functions has been extracted into a separate extension h3_postgis. Install using CREATE EXTENSION h3_postgis;.
• Enable link time optimization (see #75, thanks @mngr777)
• Handle non-polygons for h3_polyfill (see #55, thanks @Lokks)
• Take advantage of the new v4 error codes (fixes #71, thanks @kalenikaliaksandr)

v3.7.2

• Allow NULL in holes array for h3_polyfill (see #64, thanks @mngr777)
• Allow >1Gb memory allocations for h3_polyfill (see #65, thanks @mngr777)
