v0.0.10

• Update the README with post-beta 2 information (this was committed straight to the main branch after v0.0.9 so it would be visible to everyone immediately, but I did not create a v0.0.9a release with the updated README).
• Place kext patches into a "kexts" folder on the USB stick, rather than cluttering the USB stick's root directory. (This may be important if future patcher releases add more kext patches, but even for the current version it's still a nice cleanup.)
• Update AppleHDA -- it turns out that it was updated in High Sierra security updates, so this version of the patcher now uses the version from Security Update 2020-003 High Sierra (the latest as of this writing).

I considered mixing these changes with other, higher-risk changes, but decided to separate these changes into their own release. That way, if the changes in v0.0.11 turn out to be a mistake, I'll have the option of reverting the entire release rather than being forced into reverting part of the release. (It's not that reverting part of a release would be that much harder technically, but it could be harder to explain in simple terms, so that's still a reason for me to avoid it if I can.)
