inatpick 0.2.2

CRAN feedback fixes

Quoted ‘iNaturalist’ and ‘API’ per CRAN formatting requirements in DESCRIPTION
Added API web reference to DESCRIPTION
Added missing \value documentation to inat_annotations
Replaced unconditional cat() calls with message() (suppressible via suppressMessages()) in inat_fetch() and inat_search_taxon() / inat_search_place()
Removed default out_dir / path arguments from inat_download() and inat_metadata() since they wrote to the working directory by default; these must now be specified explicitly (CRAN policy)

inat_search_taxon() — search for a taxon by name and retrieve its ID; includes optional rank argument to filter by taxonomic level
inat_search_place() — search for a place by name and retrieve its ID

inat_fetch() now accepts multiple annotations as a character vector (e.g. c("flowers", "green_leaves")); each is fetched separately and results are combined with duplicates removed
inat_download() now saves metadata.csv automatically alongside photos by default (metadata = TRUE); use metadata = FALSE to skip
inat_download() file names now include the size suffix (e.g. obs123_456_large.jpg)
inat_download() prints the full output path after downloading
inat_metadata() column names cleaned up: taxon, common_name, user, user_name, place, url instead of raw API names
Fixed num_photos bug in inat_metadata() that was counting fields instead of photos
Added startup message on library(inatpick) with workflow overview
Added note on common_name locale in inat_search_taxon() and inat_metadata() documentation
