feat: support mode inputs on lsp-eslint-working-directory

[iyefrat]

eslint.workingDirectories accepts {"mode": "auto"} and {"mode": "location"} inputs (see 0). auto is particulalry important for using eslint in a monorepo setting.

There is one compile warning:

lsp-eslint.el:135:2: Warning: custom-declare-variable `lsp-eslint-working-directories' docstring wider than 80 characters

Otherwise, LGTM! :)
