Add ability to ignore files during linting

[pdehaan]

Describe the problem and steps to reproduce it:

Ref: https://github.com/mozilla/web-ext/issues/1770

When using web-ext, it looks like I can ignore files using an --ignore-files="" flag. I can't find a similar flag/API for the addons-linter.

What happened?

No API.

What did you expect to happen?

API for file ignoring (since I want to ignore a 3rd party vendor file).

Anything else we should know?

npx addons-linter --version # 1.14.0

@rpl WDYT?

@willdurand @pdehaan web-ext does integrate addons-linter as a library and to implement its --ignore-files cli option is passing to the addons-linter a function through the shouldScanFile option, and so shouldScanfile is technically the API to achieve the same thing when using the addons-linter npm package as an npm module in other projects.

It looks that there is also an explicit mention to the shouldScanfile and to scanFile options in the README.md:

• https://github.com/mozilla/addons-linter#linter-api-usage

And so this should already be supported, maybe we should tweak that section in the readme to make it more visible?

Right, updating the README sounds good.
