Updated patch contains the following changes:

- Remove comments for `DataExtractor::GetMaxU32()` and `GetMaxU64()` from `DataExtractor.cpp` and keep only the Doxygen ones in the header file.
- Restore assertion for `byte_size == 0` in `GetMaxU32()` and `GetMaxU64()`, change the assert text from "unhandled case" to "invalid byte_size" and replace `assert()` by `lldbassert()`.
- Update Doxygen documentation for `GetMaxU32()`, `GetMaxU64()`, `GetMaxS64()`, `GetMaxU64Bitfield()` and `GetMaxS64Bitfield()` to say that `byte_size` must be in interval [1,4/8] and remove that the methods return 0 if `byte_size` is bigger than 4/8 because that no longer holds. The patch retains the behaviour that LLDB does not crash in such cases but the returned value can be arbitrary. Note: This is something that I am not certain if I addressed properly. It seems to me this should be ok because the code now uses `lldbassert()` and so there will be always some error that something went wrong. An alternative is to add extra code that checks for `byte_size > 4/8` and returns 0 in such cases. Please let me know if that would be preferred.
- Enable `GetMaxU64_unchecked()` to also handle any `byte_size` in range [1,8] and add testing for this method in `DataExtractorTest.cpp`.
