feat: added P256Verify precompile to 0x100 (#126)

Closes #125 

Added `P256Verify` precompile to the `0x100` address and a test to check
its availability at both the addresses

The test is currently failing, and I'm not entirely sure about my
implementation of test function. It might be causing the test to fail.

lmk of any suggestions @onbjerg
