Probably shouldn't default to /usr/local/bin for install location

Is your feature request related to a problem? Please describe.
Looking through the install script, it currently tries to install with /usr/local/bin.
Describe the solution you'd like
~/.local/bin should be defaulted to instead; it follows the XDG Base Directory Specification and it doesn't require administrator priviledges.

Additional context
If a systemwide installation is desired(the user does something like run with sudo or passes a commandline flag), I'd opt for something under opt/ rather in /usr/local/bin, as stuff under /usr is generally reserved for system installed packages with fedora/redhat and sundry
