#109 Make package compatible with psr/log 3.0

[piotrmacha]

Description

Add additional psr/log versions to composer so the library is compabible with projects using newer psr/log version. Details as in #109

Motivation and context

It's impossible to use the library in projects with psr/log other than ^1.0. That excludes almost all modern projects with psr/log 3.0.

How has this been tested?

The existing tests pass.

Changes between psr/log major versions 1.0, 2.0 and 3.0 don't change the public interface but only add type hints according to minimal PHP versions for psr/log . The powerdns-php is using logger interface properly, so it doesn't require any code updates.
