do not consume compressed files when compression is not enabled

Is your feature request related to a problem? Please describe.

Currently filelog supports consume compressed files(gzip only at this moment), if there is no compression set in receiver config, and file pattern happens to match compressed files, it treats them as "plain" text and sends out the compressed content. Would it make sense to detect file type(mimetype) and automatically(or configurable) to stop processing files if they are not plain text?

Describe the solution you'd like

detect file mimetype and exclude compressed files

This seems like it would add some overhead just to always check for an edge case. Can the user just instead exclude files which end with extensions like .gzip?

Make sense, I think we can also use the exclude for *.gzip / *.gz files.
