[DRAFT] Update MultipleSources notebook to include projection to lonlat

[nikeethr]

resolves #95

may need @tennlee to run through this with me and edit some parts. Converting to a draft until we've gone through it.

TODO:

• fix graphviz issues (probably on my end)
• merge radar data source with other sources using pipeline (in contrast to branched/split data-sources)
• clean up documentation (currently quite wordy)
• finish "advanced" configuration section OR move it to "Future Work"

[nikeethr]

Should rebase on top of #106 once that's merged in.

NOTE: this notebook should now be updated to use #152 and/or if this PR is no longer relevant we can discard it.

We have gone through projection again and have now implemented an alternative approach which was just merged. This PR is now outdated, so closing it.
