c/sedona-s2geography: Complete function parity with BigQuery geography

A few functions are missing and need low-level implementation in s2geography to complete parity with the list of functions at https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions .

- [ST_LINESUBSTRING](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_linesubstring)
- [ST_COVEREDBY](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_coveredby)
- [ST_COVERS](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_covers)
- [ST_HAUSDORFFDWITHIN](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_hausdorffdwithin)
- [ST_INTERSECTSBOX](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_intersectsbox)
- [ST_TOUCHES](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_touches)
- [ST_ANGLE](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_angle)
- [ST_AZIMUTH](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_azimuth)
- [ST_HAUSDORFFDISTANCE](https://docs.cloud.google.com/bigquery/docs/reference/standard-sql/geography_functions#st_hausdorffdistance)

Start in the s2geography component and compare its available functions with the linked BigQuery geography-functions reference. Implement the nine listed functions at the low level, then verify that s2geography provides parity with that function list.
