SIP-compatible paths in install.sh file

[agrafuese]

Hello. After recently discovering some trouble installing ComboJack in Catalina, I realized that I was forced to install all files originally assigned to /usr/bin into /usr/local/bin instead. Advanced users may figure this out on their own, but I think it would be helpful to revise the install.sh file accordingly. Here are the paths that would be rewritten:

For install.sh...

sudo cp ComboJack /usr/local/bin
sudo chmod 755 /usr/local/bin/ComboJack
sudo chown root:wheel /usr/local/bin/ComboJack
sudo cp hda-verb /usr/local/bin
sudo chmod 755 /usr/local/bin/hda-verb
sudo chown root:wheel /usr/local/bin/hda-verb

For com.XPS.ComboJack.plist...

<key>ProgramArguments</key>
<array>
<string>/usr/local/bin/ComboJack</string>
</array>

Thank you for the release, by the way. Cheers!
