Issue reading OSTR1 matrix

[leakec]

I'm getting the following error when reading an op2 file with the OSTR1 matrix.

failed reading b'OSTR1' isubtable=-4

AssertionError: b'OSTR1'

The error is technically on an unsupported Nastran version (NX 2412.5); however, I believe it will affect all versions, as the OSTR1 matrix is a cbeam strain matrix. I was able to get this working by just including OSTR1 in the op2_codes.

I will submit a merge request with this change shortly, as it fixes the bug and allows me to read the entire file. I can also upload a reg test that reads this op2 file after the fix. I will do these in separate commits, in case it's better to split it off into a simpler unit test that just reads that matrix.

PR submitted. The op2 file I mentioned above is added to the test case in this commit of the PR.
