Fix transform() corrupting ANY columns on STRICT tables to REAL

Browse source 
column_affinity() fell through all type checks for the SQLite-specific
ANY column type and returned float, which then mapped to REAL in
COLUMN_TYPE_MAPPING. This caused transform() on a STRICT table with
ANY columns to either crash with IntegrityError (when existing rows
held non-numeric values) or silently change the column type from ANY
to REAL.

Add ANY as an explicit case in column_affinity() so it passes through
as the string "ANY", and register "ANY"/"any" in COLUMN_TYPE_MAPPING
so create_table_sql() emits the correct column type.

Fixes #790
