feat: find applications in user home directory

[PsyGik]

Not all applications are installed at /Applications. Devices where privilege access is reduced can't install apps in the root applications folder, but can install them at ~/Applications. This is a pretty standard directory across MacOS therefore can be added as an additional directory for the find command

Hi @PsyGik, apologies for the late reply; have been quite busy recently. Thank you for this! I'll merge this and get it into the next release. I'm hoping to do that tomorrow 🤞
