Release changelog for 4.3.0

[woensug-choi]

A draft we all can work on.

I've added my parts including the ones that are not on Trello.

Wow - thank you @woensug-choi and @j-herman for getting a head start on this!

I'll take the lead on it and will ask folks for details were needed. I'll ask @mabelzhang for a review once we are close and then merge it when I tag the release.

@bsb808 Do we want to merge this PR in the other repo before tagging the release? Field-Robotics-Lab/nps_uw_multibeam_sonar#38

I've just approved it. If we want, I can merge that one, otherwise we can wait for Woensug's daytime. How do we do the joint release - will that repo be tagged separately anyway?

[bsb808]

@mabelzhang Doing them at the same time would be ideal. Go ahead and merge Field-Robotics-Lab/nps_uw_multibeam_sonar#38

Field-Robotics-Lab/nps_uw_multibeam_sonar#38 has been merged

Fixed some URLs

Pending: #207
If it gets merged, should add to changelog.
Although, the relevant wiki page has already been added under "Coming Soon." So maybe the PR could get added there too.

Just moved both to the changelog, since we found the problem! Hoping I didn't just jinx it, but 207 should be merged shortly.

I'm glad I'm not the only one who believes in jinxing.

@mabelzhang - good to merge?
