Filter processing ignores the schema case-sensitivity flag

The current SArg to Filter Conversion ignores the case-sensitivity setting during read and always perform case-sensitive search of fields even when asked to perform case-insensitive match using

options()
.searchArgument(sarg, new String[] color:#6a8759}"RIDX"{color)
.allowSARGToFilter(true)
.isSchemaEvolutionCaseAware(false)

leading to the following exceptions that the field is not found in the schema

java.lang.IllegalArgumentException: Field RIDX not found in struct<f1:bigint,f2:decimal(20,6),f3:bigint,f4:string,ridx:bigint>

SArg to Filter conversion should respect the case-sensitivity option as supplied by the reader.
