obisindicators 0.2.0

Added an H3 tiling (h3t) workflow to serve indicators as on-demand H3 hexagon map tiles (see vignette("h3t")):
- build_obis_h3_duckdb() builds an authoritative DuckDB store from OBIS open-data parquet — a precomputed all-taxa indicator layer (idx_h3, res 1–7) plus a species-level store (occ_h3, tiers 3/5/7) for on-the-fly taxon/year-filtered queries. The ES50/Shannon/Simpson/richness math is the SQL translation of calc_indicators(), pinned by a new parity test.
- obis_h3t_sql() / obis_h3t_url() compose the validated read-only SELECT and the base64-encoded tile URL for the h3t service (MarineSensitivity/server/h3t) and mapgl::add_h3t_source().
- canonical SQL in inst/sql/; server build driver in data-raw/build_obis_h3_duckdb.R.

Renamed functions for consistency:
- calc_es50() -> calc_indicators()
- gmap_metric() -> gmap_indicator()
Fixed gmap_indicator() to use default Robinson projection.
Updated vignettes with name changes and use of “indicators” over “metrics”.
Supplemented documentation for calc_indicators() with expected input and output columns to data frame.
Added documentation for occ_fk and occ_1960s to occ_2010s
Made generation of occ_* datasets more reproducible with set.seed() and sampled versions of dataset to minimize file size on Github in data-raw/occ.R.
