Naming inconsistencies - Rename the compile parameter from dir to path

[Daniel-K-Ivanov]

Currently there are inconsistencies for the naming of different parameters. For example:
When doing compile, the parameter for the path is dir

etherlime compile --dir {dir}

When testing, the parameter is path.

etherlime test --path {path}

When using coverage the parameter is path as-well

and when deploying the parameter is file

etherlime deploy --file {file}

For the deploy, it is okay to be file, however when it comes to directories, I think it would be best to have consistent naming of the parameters, because everytime I do compile or test, I go into the docs and whether I needed to do dir, path or file

Proposed solution:
Change the etherlime compile parameter to path as-well
