Update latest to v4.0 of flightaware/dump1090

[e2jk]

Specifications

• Image hash or version: latest/1.3.1
• Platform: Raspberry Pi 1B (old ;) ), armv6
• Subsystem: ?

Expected Behavior

I would expect the latest tag of this repo on the Docker Hub to use v4 of flightaware/dump1090.

Actual Behavior

The image currently pushed (one month ago) to the Docker Hub with tag latest is version 1.3.1 of this repo, which uses v3.8.1 of flightaware/dump1090.
There is an older (5 months ago) tagged flightaware-v4.0 which, based on its name, I'm assuming is using v4 of flightaware/dump1090.

Shouldn't latest point to v4?

Steps to Reproduce the Problem

1. Install from Docker Hub targeting the latest tag
2. Run and noticed that on the webpage it indicates v3.8.1 in the upper right of the page. I'd have expected v4.0

Hello v4 has a bug #35, so I'm waiting for the fix (that is already on master, but no release yet...).

Merci @Thom-x.
I do see there are quite some changes on their dev branch (86 commits since v4.0), for now I'm compiling with v4.0 on my Raspi 1B to confirm flightaware/dump1090#115 is fixed in v4.0. Slow machine, but we'll get there at the end of day ;)
