Settings View Source Cachex.ExecutionError exception (Cachex v3.6.0)

Minor error implementation for all Cachex-specific errors.

This module allows users caton catch Cachex errors in a separate block to other errors/exceptions rather than using stdlib errors.

iex> try do
...>   Cachex.put!(:cache, "key", "value")
...> rescue
...>   e in Cachex.ExecutionError -> e
...> end

The default error message should always be overridden with a long error formas displayed inside Cachex.Errors.
