Previously, the launcher will try to redownload the entire patch files if say, the user tried to cancel the patch-update process, even though some target files have already been patched/updated. Now, the launcher will try to check for target file hash/existence before downloading the patch file. If the hash (of the target file) matches, then skip the patch process.
DirectoryInfo.Create() already contains a check for directory existence on PInvoke level.

Main Goal
This change contains a bug fix where the deleted assets inside the game get redownloaded during a game update. Previously, the filtering for the deleted assets were done by comparing the URL which contains the
MatchingFieldstring. However, the URL structure has changed and theMatchingFieldstring got removed, therefore the launcher is unable to identify which assets can be ignored.We are adding a new class inside our Sophon submodule called
SophonIdentifiableProperty, which contains some necessary fields needed to compare the asset's category and where the asset came from.See related Issue: #850
