Updated installer to remove dependence on pi user account. You do NOT need to update to this version if you have an installed version already. This is just to accommodate changes in the Raspberry Pi OS default installation.
In the meantime, found some really interesting bash scripting issues which needed to be corrected. The new installation command is:
bash <(wget -O - https://raw.githubusercontent.com/nebhead/spkr-select-v3/master/auto-install/install.sh)
