Added the ability for a remote reporter to response with {:error, reason, new_state}.

v0.5.0 - 2022-05-31

Breaking changes for three functions in the Mobius.Exports module:

If you are now directly calling these functions in code you're safe to upgrade.

The first two use to return either {:ok, results} or {:error, reason} but now they will only return their result. For Mobius.Exports.series/4 the return value is now [integer()] and for Mobius.Exports.metrics/4 the return type is now [Mobius.metric()]. Mobius.Exports.plot/4 still returns :ok on success, but can now return {:error, UnsupportedMetricError.t()}.

Changed

Mobius.Exports.series/4 return type was {:ok, [integer()]} | {:error, UnsupportedMetricError.t()} and now is [integer()].
Mobius.Exports.metrics/4 return type was {:ok, [Mobius.metric()]} | {:error, UnsupportedMetricError.t()} and now is [Mobius.metric()]
Mobius.Exports.plot/4 was just :ok but now is :ok | {:error, UnsupportedMetricError.t()}
