Increase the timeouts to be 60 instead of 6.
The reason for this is that some controllers (like the Zephyr
controller) will reserve some of these to ensure stability,
and in fact with skip = 5 and retry = 6, it would still
send the PA reports at every interval.
To accomodate a higher timeout value, the functions used to
convert PA intervals to PA timeouts have been updated.

The bt_iso_chan_send function could take an optional
timestamp by using 0 as an indicator. The issue with
this approach was that a timestamp value of 0 is valid,
and could cause potential issue with syncing streams
in a group.
To fully support transmitting with and without timestamp,
bt_iso_chan_send_ts has been introduced, which is the only
function of the two (bt_iso_chan_send being the other) that
supports timestamps.
A new function, rather than adding a boolean to the existing,
was chosen as it simplifies the individual functions as well
as making it more explicit what the function does.
Since the bt_iso_chan_send function is used by LE audio, both
the BAP and CAP send functions have similarly been updated.
Likewise, all tests and samples have been updated to use the
updated function(s), and BT_ISO_TIMESTAMP_NONE has been
removed.

more or larger BASEs.
2) The functions to parse BASEs now support arbitrary sized
BASEs, where they were previously restricted by our

from a remote device, without encounting memory issues.
We are still memory restricted on the devices we

Add support for transmitting on multiple streams, e.g.
with the simple `send` command or with the sine generator.
This extends the start and stop sine to take a "all"
paramter to start sending on all streams.
This also fixes an issue with the seq_num when multiple
streams are transmitting, since the timing may get delayed
which then delays the seq_num which are then scheduled too late.
The fix here is to only use the timer for the inital sequence
number when starting to send the sine way, and then increment it
per TX.

Previously the calculation of the PSN was done using
just a timer. This would not work correctly when
attempting to send multiple packets in a single SDU
interval (e.g. to enqueue 2 or more).
Previously we only ever attempted to send 1 packet in
the `sent` callback but scheduling the work item. However
in the case that the `sent` callback was called twice
before the work item had been triggered (possible due
to the priority of the RX thread being higher than the
system workqueue thread). This has been modified so that
if we can enqueue more packets in the lc3_audio_send_data
function, we re-enqueue the work item. We re-enqueue rather
than sending multiple in a single call to avoid blocking
other items on the system workqueue from being scheduled.
This could cause possible missed intervals (if other workqueue
items are processed), but it should be OK from a ISO perspective,
and the new PSN calculator handles this much better.
