Create general Excel/csv -> yaml conversion script

[BoergeSt]

for large projects, the config.yaml file can become quite large und confusing. Therefore we used a simple convertion script in the past in order to convert excel or csv files into config.yaml files. While this worked very well, it is annoying to write such a script for every project. Therefore we came up with the following csv format:

A header Line:
| <Type 1> | Name | <property 1-1> | <property 1-2> | .... | <property 1-N> | | | <Type 2> | Name | <property 2-1> | <property 2-2> | .... | <property 2-N> |
multiple node description lines, read from left to right. If name is identical, the node is reused, if a property isn't given, and the node has not been initiated yet, leave the property out.

At Least One Space
Same as above => New Header and new node description lines,

Repeat!
