List checksums & downloads for all published/released APKs/IPAs

[emanuelb]

While work in issue #252 will document patches to rebuild old apk versions, the matching will be done against the published apks in github releases at: (under Assets as app-release.apk or Hamagen-[tagname].apk)
https://github.com/MohGovIL/hamagen-react-native/releases

The needed match need to be done against apks released in google-play-store, but they don't provide api for downloading info on past versions (it's also possible to target different countries / languages / devices, and beta enrolments with different apks)
So another source of apks would be downloaded sites, such as (they are not endorsed) :
https://apkpure.com/%D7%94%D7%9E%D7%92%D7%9F-2-%D7%94%D7%90%D7%A4%D7%9C%D7%99%D7%A7%D7%A6%D7%99%D7%94-%D7%94%D7%9C%D7%90%D7%95%D7%9E%D7%99%D7%AA-%D7%9C%D7%9E%D7%9C%D7%97%D7%9E%D7%94-%D7%91%D7%A0%D7%92%D7%99%D7%A3-%D7%94%D7%A7%D7%95%D7%A8%D7%95%D7%A0%D7%94/com.hamagen/versions
https://apkplz.net/app/com.hamagen

having official list (such as someone with read-access to google-play-store logs/versions history) would be better.

Only Release APKs are relevant (built from assembleRelease task using official certificate)
(not APKs built from assembleQa or assembleDebug tasks)

SHA256SUMS APKS:
TBD - Add more versions!
07c5b7b648325a4eea286d168e2f9ea414c59bd9ab283030be3d521816a46f9d 1.2.4 - NOT VERIFIED

It will show "VERIFIED" instead of "NOT VERIFIED" where there will be shown how to reproduce this binaries from source-code from github (reproducible builds), which means usage of Containerfile, tracked at issue: #243 and needed patches tracked at issue: #252
