Allow additional user input and default to best practices for to-gpq and to-cog

[bjyberg]

In general, this library is very opinionated and does not leave many options open to the user. Implementing the below would make it more useful and have better defaults.

Scope:

• to-gpq

  • Implement GeoParquet best practices

    • Use ZSTD compression
    • Sort based on bounding box
    • Apply other recommended optimizations

• to-cog

  • Add option to disable overview generation (e.g., via a flag/command)
  • Add options to specify compression algorithm
