Wrong coordinates in juelich-tower-measurements.json

Wrong coordinates in juelich-tower-measurements.json
A clear and concise description of what the bug is.

To reproduce
Steps to reproduce the behavior:

1. Open juelich-tower-measurements.json,
2. Go to coordinates
3. Transform coordinates to offsets in m with utils.calculate_heliostat_position_in_m_from_lat_lon

Expected behavior
The solar_tower_juelich_upper center coordinate should be something like [0, 0, 50] but deviates greatly.

Additional context
The utils functions to transform the coordinates were tested and seem to be right.

@kalebphipps I looked into the problem and noticed the following:

We have two functions: calculate_heliostat_position_in_m_from_lat_lon (converts lat/lon to meters) and its reverse (converts meters back to lat/lon). When calculating both directions from the coordinates [50, 50, 50], the results differ slightly, resulting in [49.98, 49.98, 50]. I plan to investigate this further at a later stage.

However, what I don't quite understand is why, when using the lat/lon -> m direction with values such as solar_tower_upper_center, the resulting values differ significantly from those initially provided in the CSV document. Could you provide some insight into this?
