perf(decompress): Batch column drops + docs(draw): Add draw_help()

1. perf(decompress): Batch column drops in decompress_columns()
   Individual df.drop() per column caused O(N_cols × N_rows) pandas
   reindex. For 7 columns × 82M rows: 12s out of 17s total.
   Fix: Collect columns, drop once after loop. 17s → ~5s.

2. docs(draw): Add draw_help() bridge to dfdraw documentation
   adf.draw_help() lists plot types, adf.draw_help('profile') shows
   full dfdraw parameter docs. All convenience methods updated.
