Trying to assemble the instruction addi t0, t0, 0xEEE results in an operand is out of range error, even though the number 0xEEE has 12 bits, therefore complying with the RISC-V specs for I type instructions.

This is a duplicate of #103 and #5.

TLDR: Write the sign-extended value. addi t0, t0, 0x00000EEE is not a possible instruction so RARS rejects it.
