RAM-SCB won't compile under GCC10

[drsteve]

Two issues here:

1. As noted in SWMF/share library is out of date #78 the share library is out of date. One of the changes removes setting an octal mask which is now prohibited under GCC10. This can be solved in the short term by adding the -fallow-invalid-boz flag, but this flag (if added) should be removed when the share library is updated.
2. Interfaces in our dependencies now trigger a strict check for argument mismatches, leading compilation to fail. Under GCC10 these can be converted to warnings by adding a new flag: -fallow-argument-mismatch.
