At the request of @josepll, this release incorporates the bug fixes that have been made over the last year.

Namely the bugfixes are:

• Fix funct field on BLTU, BGE, and BGEU

• Removed compact psuedo-ops code (because it wouldn't work with riscv anyway)
• Fix la and friends in the aftermath of the auipc fix
• Fix bug where AUIPC used PC+4 instead of PC
