Add accessor functions for the callback data structs from the C API

> It seemed like a good idea to introduce `const char*` definitions such as `kHighsCallbackDataOutLogTypeName` in `highs_c_api.h` so users pass these rather than explicit strings as the `name` argument, but...

Add accessor functions for the callback data structs from the C API

@cyderize Please would you let me know if what's in #1748 is what you had in mind. It would also be great to understand why the `const char*` definitions in...

Add accessor functions for the callback data structs from the C API

Many thanks @cyderize , I'll keep the single method and passing names for consistency with other such methods. Thanks for the 'const char* const' tip: I've not grown up writing...

Assertion `model->col_upper_[col] == kHighsInf || (model->col_upper_[col] >= implColUpper[col] - primal_feastol && colUpperSource[col] == row)' failed.

I note that it says "options file not found", so if you're wanting to reproduce options settings that you make in your application, it's not picking them up. I didn't...

Assertion `model->col_upper_[col] == kHighsInf || (model->col_upper_[col] >= implColUpper[col] - primal_feastol && colUpperSource[col] == row)' failed.

I see that your MPS file has plenty of full-length values. The option you describe would be relatively easy to implement. I'm puzzled as to why that "Options file not...

Consider removing `Highs_compilation_date` to improve build reproducibility

`HIGHS_COMPILATION_DATE` is no longer printed in the logging header at run-time - only `HIGHS_GITHASH` - but are you referring to it appearing in build files like `HConfig.h`? I've got no...

Consider removing `Highs_compilation_date` to improve build reproducibility

OK, I think I understand. Although a hard-coded date is only created in the text file `HConfig.h`, the actual value of `HIGHS_COMPILATION_DATE` is in the binary, so this changes if...

Consider removing `Highs_compilation_date` to improve build reproducibility

Thanks @odow, @galabovaa will remove all reference to `HIGHS_COMPILATION_DATE `, and > const char* highsCompilationDate() will return a "Not known" message, and be deprecated
