Backup fails for large repos with many files and large number of versions

[nycnewman]

The current process only looks for packages and then files within packages. For large repos the package retrieval can take a long time (we have hundreds of versions) and then the package file list never returns (error from bintray). Alternative approach would be to parse the versions within a package and request file list per version per package.

Sadly my Kotlin is non-existent otherwise would try to provide a Pull Request.

https://bintray.com/docs/api/#_get_version_files

i.e.

• get list of packages within repo
• for each package get package details and parse versions
• for each package/version get list of files
• download files
