Extendable "Protocol" and "TechnicalAssetTechnology" classes - move to yaml files

[Thorsten-Sick]

Create a "protocols" folder and a "technicalassettechnology" folder. In there define the protocols and assets as ,yaml files (one for each protocol/asset.

The code for the protocols/assets can then be removed from types.go

That way everyone can extend Threagile in a simple way. And especially protocols and TechnicalAssets are growth-candidates.

Currently those are defined in the code. And there are several functions defining the features of those. isEncrypted is an example. This can just be a bool value for the protocol description yaml.
