Add GOES-19 RGB2XYZ matrix for true_color_reproduction

[simonrp84]

Adds theRGB-to-XYZ conversion matrix required by the true_color_reproduction composite for the GOES-19 spacecraft. This satellite was previously missing. Note: Matrix is not optimal as GOES/ABI misses a green band, and hence here we use a hybrid matrix that assumes the value of the green band computes for GOES/ABI.

• Closes No conversion matrix found for platform GOES-19 #3053

NOTE: I haven't had a chance to try this on actual G-19 data, but as the values are close to those for the other GOES satellites I expect it to work fine. I suggest not merging until we get feedback either from the user in #3053 or from someone else who gives this a go with the real data.

I have now tested this with GOES-19 and it correctly generates the true_color_reproduction composite as expected. Therefore, this PR is ready to merge as (I think) the one test failure is unrelated and is happening on all the other PRs too...

[gerritholl]

Could you post an example image?

[gerritholl]

I also prefer the standard true_color one, but as I don't use true_color_reproduction I won't stand in the way of anybody who wants to use it like this.

[simonrp84]

I slightly updated the matrix due to an error in my code. New one committed now!

It made very little difference to the images compared to those shown in my (now deleted) previous comment. Top, true_color. Bottom, true_color_reproduction.

Looks good to me!
