Add new findOrigin functionality

Adds Origin value object which is returned by Debug::findOrigin to be able to determine the origin call without necessarily creating an exception. We refactored the Debug class accordingly.

Refactoring + namespace ignore feature

The Debug class was heavily refactored and it is now possible to ignore namespaces when creating an exception. This is also a BC-break, as the arguments for Debug::createException have changed with this new option.

Stable release with documentation

This is a mini-library mainly for other libraries, but the limited scope should be stable. We set the minimum PHP version to 8.0 - v0.5.5 can still be used for anything below 8.0.

v0.5.5

Add missing type hints to OriginException

v0.5.4: Avoid mb_check_encoding deprecation

Appeared with PHP 8.1 when the value null is passed
to mb_check_encoding by accident.

v0.5.3

Fix unclear types & PHPStan issues

Allow PHP8

Change version constraint and configuration to allow PHP8.

Improve exception origin

• Default file and line of the exception now points to the
  origin instead of where the exception was thrown (which
  never helps, as it is always the same place with our
  Debug class)
• We preserve the actual location where the exception was
  thrown on the off chance that it might still be needed
  or useful in some circumstances

v0.5

First official release
