v1.440: C-QUAM & channel queueing/camping
From the CHANGE_LOG file:
v1.439,440 March 14, 2021
Channel queuing and camping:
When all the Kiwi channels are busy(*) it is now possible to enter a queue to wait
for the next available channel. The queue is FIFO and multiple parties can
occupy the queue (your queue order will be shown).
If all channels are busy you can also now "camp" on an existing connection and
hear the audio of that channel. The only adjustment is to change the audio volume.
Otherwise you experience all the changes performed by the owner of the channel
(tuning, mode, etc).
You can also be in the queue waiting for your own channel while camping.
It is possible to use camping even if free channels are available by connecting
using the URL parameter "camp", e.g. my_kiwi:8073/?camp
You might want to do this if you know there is already a connection you want to
camp on, but there are also free channels you don't want to unnecessarily occupy.
In theory camping requires only slightly more resources because the audio stream
is simply being duplicated and sent to the camper's network connection.
The Kiwi admin can configure the maximum number of campers allowed, including zero.
Later on we can look at adding audio-related features to camping that only require
(e.g. S-meter, recording, audio FFT waterfall/spectrum display).
These changes are complex and will no doubt have bugs and corner cases to fix.

Added C-QUAM AM stereo mode to SAM mode button which now cycles as: SAM/SAL/SAU/SAS/QAM
Based on the work of Github user MaPePeR, see: github.com/jks-prv/Beagle_SDR_GPS/issues/395
Remember that alt-click will toggle the mode buttons backwards, e.g.
alt-click on SAM wraps back to QAM (faster than clicking forward on SAM 4 times).
The same applies to the keyboard shortcut: shift-A is SAM mode forward to SAL
alt-shift-A is SAM backward to QAM.
Apply ITU region selection to band display (e.g. 40m ham band now stops at 7.2M for R1)
It is possible this change will cause problems if extensive customization of
the kiwi.config/config.js file has been made by the user. Please let us know if
this happens to you.
