Generalization of Transmission plugin

[ka-sarthak]

Based on the discussions during AreaA TF today, we can generalize the Transmission plugin in the following steps -

• [x] Identify the general components in Hiroki's UV-Vis Transmission schema
• ~Classes like UVVisNirTransmission and InfraRedTransmission can extend Transmission in the nomad_measurement plugin. One can alter the default units of the wavelength based on the popular choice of units for the particular community (UV-Vis or InfraRed).~
• [x] Not making an intermediate Transmission class. Different flavors of transmission directly inherit Measurement
• [x] Create wrapper classes for Transmission in the IKZ_plugin folder. The IKZ-specific parsers (.asc) and normalizations can be added here. https://github.com/IKZ-Berlin/nomad-ikz-plugin/issues/1

@budschi @hampusnasstrom @aalbino2 what are your thoughts on this?

• [x] Add tests for the schema just like in XRD
