[pojiro]

This fix following error.

=SUPERVISOR REPORT==== 23-Jul-2022::07:54:11.942998 ===
    supervisor: {local,kernel_sup}
    errorContext: start_error

                        "Library module name 'Elixir.Circuits.GPIO.Nif' does not match calling module ''Elixir.Circuits.Cdev.Nif''"}}}
    offender: [{pid,undefined},
               {id,kernel_safe_sup},
               {mfargs,{supervisor,start_link,
                                   [{local,kernel_safe_sup},kernel,safe]}},
               {restart_type,permanent},
               {significant,false},
               {shutdown,infinity},
               {child_type,supervisor}]

How about make new tag 0.2.0 as renamed library?
