psgc 0.1.1

island_region values are now consistently abbreviated ("L", "V", "M") across all releases. Three older releases (Q4_2023, April_2024, Q2_2024) had full spellings (“Luzon”, “Visayas”, “Mindanao”) which are now recoded during the data build step.

get_psgc_wide() returns a denormalised wide-format data frame with one row per barangay and all four geographic levels (region, province, city/municipality, barangay) spread into columns. HUC/ICC barangays have city_mun / city_mun_code set to NA; areas with no province layer (e.g. Pateros, City of Isabela, Special Geographic Areas) have province / province_code set to NA (#get_psgc_wide).
map_psgc() gains a changes_only argument. When TRUE, only rows where the code actually changed (mapping type is not "direct") are returned, making it easy to identify renumbered or abolished codes across releases.

map_psgc() has been rewritten with a fully vectorised algorithm. The crosswalk is pre-split by hop once per call and all codes are processed simultaneously at each hop using match(), replacing the previous per-code loop. This yields roughly a 500× speed-up for large code vectors (e.g. 1 000 codes: 94 s → < 0.2 s).
