[Bug] Fix boolean parsing for yes/no string values (#3346) (#3365)

When loading GeoJSON data containing boolean fields with "yes"/"no"
string values, type-analyzer correctly classifies the field as boolean,
but the kepler.gl parse function only recognized "true"/"True"/"TRUE"/"1"
as truthy. This caused all "yes" values to be incorrectly parsed as false.

Align the boolean parse function with type-analyzer's boolean recognition
by using case-insensitive comparison via String.toLowerCase(). The parser
now correctly handles "yes"/"Yes"/"YES" as true and "no"/"No"/"NO" as
false, matching the BOOLEAN_TRUE_VALUES and BOOLEAN_FALSE_VALUES defined
in type-analyzer.

Also expand boolean test coverage to include yes/no variants and
additional case combinations (TRUE, false, FALSE).
