Fix RSP instruction decoding (#4)
* Use the proper registers on RSP GPR instructions

* Add IMM_base operand to RSP instructions

* Use `ra` on RSP GPR registers

* Fix RABBITIZER_OPERAND_TYPE_RSP_rd

* ??

* fix vector register element index

* fix RSP mfc2 and mtc2

* fix vmov and similar instructions

* format

* update readme

* version pump
