Feature request: Allow setting default values for MtXLoader

[SupportC6]

Hello,

Thanks for your great work on ng-matero and its extensions!

Currently, MtXLoader does not seem to support setting default values globally (e.g. colors, loading type, etc.), unlike what Angular Material allows via configuration or injection tokens.

Would it be possible to support a way to define default values (e.g. through a provider or a configuration module) to avoid repeating the same inputs in each usage?

Thank you for considering this enhancement!

You can also use the Material global configs. Do you try the MAT_PROGRESS_BAR_DEFAULT_OPTIONS and MAT_PROGRESS_SPINNER_DEFAULT_OPTIONS?
