[feature request] excluding files/folder by name

[afmahmuda]

problem
currently, only ignore non .go files and _test.go files
suppose i have _mock file inside the same folder, said mock will pollute the the whole graph

how to reproduce

generate mock file inside target folder / sub folder

proposed solution

1. option to ignore file by name, eg. ^.+mock$
   or
2. option to ignore generated files
   or
3. ability to ignore folders

[afmahmuda]

before going to implementation, i would like to ask your opinion on which solution will be better, of if you have a better solution

Hi @afmahmuda thank you for contributing!
I would rather go with ignore_regex where users can ignore folders or files by using a regex.
