Add functionality to differentiate between multiple target symbols in config.yml add_relocations

[TheNathannator]

Currently, there is no way to disambiguate between multiple symbols of the same name when adding relocations via config.yml. A very notable case would be adding a relocation to a string pool, as there could be hundreds or thousands of @stringbase0 symbols that exist in a project.

This could be done by splitting the target field into two targetName and targetLocation fields, which hold the symbol name and address respectively. There could also be some way of combining the two fields (this is what I instinctively tried in the config.yml - @stringbase0:0x80b895e8), but it could be difficult to determine where the symbol ends and where the location begins.
