Solver crashes instead of reverting to MUMPS

[jamesmurdza]

I can’t tell if this is an existing issue or one I have introduced in my recent changes. I’m sure that installing the appropriate libraries would fix the issue, however it should not be crashing.

Works:

dice = solve(BasePrice, version, linear_solver = mumps);


Fails:

base = solve(BasePrice, version)

Exception of type: DYNAMIC_LIBRARY_FAILURE in file "Common/IpLibraryLoader.cpp" at line 67:
 Exception message: libhsl.so: cannot open shared object file: No such file or directory

EXIT: Library loading failure.

Thanks for the changes! Yep, I'll take a look and see, but the expectation is that not finding hsl would fallback to mumps by default. This shouldn't happen.

Fixed in #45
