Add the ability to build filters completely locally

[Alex-302]

To simplify the checking of changes in the filters compiler, it is necessary to be able to test different versions of the compiler with the same version of raw filters.

That is, first it is necessary to do full processing to download all filters, and then diffs can be compared (without redundant changes added to the filters between compilations of the filters).

Add an ability to:

• download filters and save them locally
• run filters build with downloading from the server and with using local files (if no local files - download)
