Some chips require EWSR before WRSR, others require WREN before WRSR,
and some support both variants. Add feature_bits to select the correct

Some chips implement the RES (0xab) opcode, but they use a non-standard
two byte response instead of the usual one byte response. A two-byte
response has the accuracy of REMS and RDID, so don't check for REMS/RDID
availability before running a two-byte RES.
