Cast "1" and "0" as booleans when they are expected as booleans.

[aaronjorbin]

Rollbar/WordPress/UI creates checkboxes for booleans and stores the state as "1" and "0". The PHP8 version of https://github.com/rollbar/rollbar-php expects actual booleans. this updates the config builder to convert "1" and "0" into TRUE and FALSE.

Fixes: #119
