Functions for Reporting SNMP Errors on stdio

The module `snmpa_error_io` implements the `snmp_error_report` behaviour (see `snmpa_error_report`) containing two callback functions which are called in order to report SNMP errors.

This module provides a simple mechanism for reporting SNMP errors. Errors are written to stdout using the `io` module. It is provided as an simple example.

This module needs to be explicitly configured, see snmpa_error and configuration parameters.

## Summary

### Functions

config_err(Format, Args)

The function is called if an error occurs during the configuration phase, for example if a syntax error is found in a configuration file.

user_err(Format, Args)

The function is called if a user related error occurs at run-time, for example if a user defined instrumentation function returns erroneous.

## Functions

# config_err(Format, Args)

    -spec config_err(Format, Args) -> snmp:void() when Format :: string(), Args :: list().

The function is called if an error occurs during the configuration phase, for example if a syntax error is found in a configuration file.

`Format` and `Args` are as in `io:format(Format, Args)`.

# user_err(Format, Args)

    -spec user_err(Format, Args) -> snmp:void() when Format :: string(), Args :: list().

The function is called if a user related error occurs at run-time, for example if a user defined instrumentation function returns erroneous.

`Format` and `Args` are as in `io:format(Format, Args)`.
