Allow usage in an OTP supervision tree #59
Description
Currently, pog stores the PID of the pgo connection pool gen_server in an opaque type, so it's not possible to add pgo to an OTP supervision tree, and the gen_server runs unsupervised.
It would be nice if there was a pog.supervised function for usage with gleam_otp@1.
I'm not entirely sure about the design for such a function, specifically how it would allow one to still use the pog.Connection in other children of the supervisor – would appreciate some thoughts / input :)
