feat: Implement remaining parameters for ST_Buffer #223
Description
Here's the original commit that implemented basic support for ST_Buffer: 0de00cb
Currently, it simply creates and uses the default parameters
sedona-db/c/sedona-geos/src/st_buffer.rs
Lines 57 to 62 in df8f720
We should support the buffer style parameters as user input (following PostGIS syntax, not Sedona)
https://sedona.apache.org/1.8.0/api/sql/Function/#st_buffer
https://postgis.net/docs/ST_Buffer.html
The wording can be a bit misleading / ambiguous in the original PostGIS docs, so it may be worth looking at this bug fix in the original Sedona to understand the proper behavior.
