AP_RangeFinder: Add JRE-30 radar support

[rmackay9]

This adds support for the JAE-30 radar which is a 30m radar from Japan Aviation Electronics.

This replaces PR #25377 but I've made a few mostly small NFC tweaks including:

1. shortened the DIST_MAX_CM definition from 50000cm to 5000cm (e.g. 50m). This is the max distance shown when out-of-range.
2. removed an unused variable
3. added some comments
4. changed the crc loop to use uint32_t instead of "int"
5. only enabled on boards with > 1MB of flash

I've tested this fairly thoroughly including confirming the status changes correctly including when the radar is pointed up into the sky where it sees nothing.

BTW, during the review of the previous PR we decided to re-work the state machine. The original author went ahead and did that and although it's still a little different from how we normally write these parsers I think it's close enough.

The corresponding wiki PR is here ArduPilot/ardupilot_wiki#5546

We usually have included a simulated rangefinder for all the recent serial rangefinders that were merged

I've re-tested and it all seems to work fine, thanks @peterbarker!
