OpenTelemetryDecorator: add OpenTelemetry traces with one line of code

Yesterday I published my first hex package! A decorator macro that lets you add an OpenTelemetry trace to a function, (and specify span name and attributes) with one line of code. For example:

@decorate trace("add", [:a, :b, :result])
def add(a, b), do: a + b

Credo, a new static code analysis tool that acts as a code linter, but also focusses on teaching coding practices and code consistency.
