`generator.generate_slice_for_vector` function only handles .c files.

[RobotSail]

Hello,

I recently ran into an error generating a patch for a repository where changes were made to both header and implementation files. It seems like the error is rooted in the implementation of the generate_slice_for_vector function in app/tools/generator.py, where it expects the vector path to contain a .c file:

def generate_slice_for_vector(vector_path, use_macro=False):
    # ...
    source_file, segment = vector_path.split(".c.")
    # ...

However, this breaks when FixMorph passes it a vectorfile that was constructed from a header file: /dirs/iotop-c-a/src/iotop.h.func_humanize_val.vec:

                        [ERROR] Crash during finding segment clones in target, after 0.100 minutes.
                        [ERROR] Transformation Failed
                        [ERROR] not enough values to unpack (expected 2, got 1)
                        [ERROR] Unexpected error during finding segment clones in target.
                        [ERROR] Runtime Error
                        [ERROR] Error. Exiting...

To update this issue, after introducing logic to properly handle whether a file is a header or source,
I was then met with this error output:

                        [ERROR] [error] neighborhood not found

                        [ERROR] Error. Exiting...

The logic I introduced was simply:

def determine_splitter_from_filepath(fp: str) -> str:
    if ".c." in fp:
        return ".c."
    if ".h." in fp:
        return ".h."
    raise Exception(f'could not determine how to split path: "{fp}"')

Which would then be used like

def generate_slice_for_vector(vector_path, use_macro=False):
    # ...
    splitter = determine_splitter_from_filepath(vector_path)
    source_file, segment = vector_path.split(splitter)
    # ...
