Simplify flow w/ LINQ

[HebaruSan]

Thanks for the PR! Some suggestions for the implementation...

• When we throw, use Kraken because that's what Netkan uses otherwise
• Don't throw if the remote version file has an array with no matches, since that should be fine
• Gather the AvcVersion objects in one statement and process them in a uniform way regardless of format
• Fix ancient misspelling of "preferrentially" 😁

Do these changes look OK to you?

It looks like the exception is always going to get rescued right there anyway so the exception class doesn't actually matter does it?
