Laytec in situ measurement plugin

[aalbino2]

we have some room for improvement:

• update plotting with plotly library
• separate Temperature and Reflectance plots
• separate each reflectance curve plot, make also a plot showing all together (or allow for interactive switching of curves in the plot if possible)
• from the raw file, parse the metadata field ##WAFER_LABEL and include it into filename and entry name
• harmonize classes names removing underscores and making them properly pascal case
• add the post processing to clean from the noise (pick @ThomasTSC code)
• add the post processing to simulate the curve from a phenomenological optical model (to be done as soon as @ThomasTSC will refine his code)

@budschi we can start with these points, together to yours:

• link the sample in the measurement
• please add here further points
