* initial commit * most of the code done * made global poseidon chip * changed decompSize and added some panics * made all gl chip as pointers * working code * revert go.mod and go.sum * cleanup and comments * cleaned up range checker selection * renamed gnarkRangeCheckSelector to gnarkRangeCheckerSelector * addressed PR comment * addressed overflow issue identified by Veridise * added some comments * fixed some comment typos * restore change made from commit hash 85d20ce and 9617141
