mapnhanespa 0.3.0

Added an explicit map of accepted measure names to the nine NHANES summaries, including total_ac and total_activity_counts. The new nhanes_pa_measure_map() lists all supported names, and nhanes_pa_measure_cdf() selects a CDF for a measure and stratum.
Unmapped measures now produce missing quantiles with a warning that lists each unique unmapped name. steps_sdt is unmapped because no corresponding NHANES CDF is available.
map_nhanes_pa_quantiles() now adds age_category_pa_map to show the age category used for each observation's CDF.
Expanded the README and vignette examples to cover all nine supported summaries while retaining the three-participant example.
