v4.0 regex for identifying Thumbor request does not work

[soupy1976]

The regex for identifying Thumbor requests has some problems:

const matchThumbor = new RegExp(/^(\/?)((fit-in)?|(filters:.+\(.?\))?|(unsafe)?).*(.+jpg|.+png|.+webp|.+tiff|.+jpeg)$/);

    There are a couple of issues with this regex:
    - The first part is pointless, because all of the alternatives are optional, and it then does a match on anything .* - so first part has no effect as it matches anything anyway
    - The list of image file extensions is an unreliable way to match the path. For instance, I had an issue with a jpg where the file extension was capitalised.

Also this regex doesn't match tif files (single f).

Personally I think this should match json, then fall back to thumbor style.
I had to change the code because the images I was using do not have any extension
