In general, my preference for formatting is to use 4-space indentation always (not a fan of traditional erlang/emacs formatting).
Some examples:
Map = #{
foo => bar,
bar => tapas
}.
PropList = [
{foo, bar},
{bar, tapas}
].
Fun = fun() ->
// do something
end.
%% file that be consult'd
{foo, [
{bar, [
{tapas, [one, two three] %% if it fits 80 cols
]}
]}.
nested(
function(
call([if, I, am, being, anal])
)
).

This PR fixes the initialization routine that allows the rest of the interface to work. It also wraps the I2C operations using the
i2c_businterface provided by atomvm_lib.This is a convenience wrapping since most devices with an OLED display will usually share the bus with more I2C devices.
The driver does not (yet) provide the rest of the features the NIF version provides, mainly displaying bitmaps and QR codes.
Further PRs will be aimed to address feature parity, cleaning up the configuration API, documentation and initialization options.
