* Use unsigned long when dealing with millis() and micros().
Although sizeof(uint32_t) == sizeof(unsigned long) on Arduino, this is
not the case on 64-bit Linux, where sizeof(unsigned long) ==
sizeof(uint64_t).
Most timestamp arithmetic and comparisons have been left alone, to
reduce code churn. This is fine, as uint32_t is perfectly wide to store
most timestamp deltas this library will deal with, and C will promote
the integer rather than do a narrowing conversion. The real problem
arises with narrowing conversions being done by assuming timestamps are
32-bit.
No functional changes intended for platforms where sizeof(uint32_t) ==
sizeof(unsigned long) (so most 8/16/32-bit platforms).

* Change most timestamps to use RadioLibTime_t.
This makes it obvious what is and isn't a timestamp.
Not everything has been converted; anything dealing with protocol and
chip-level timestamps has been left alone on purpose, to make it clear
that these functions do require 32-bit timestamps.

* Use uint32_t internally in getTimeOnAir.
We need to not overflow the integers with the shifts and
multiplications, so this is correct behaviour.

* Addressed feedback on CSMA implementation
* symbolNumValues[6] array no longer needed as we will utilize only two symbol CAD operations for all SFs.
The SX126x get status command returns a single status byte. The status
byte is automatically read in the `Module::SPItransferStream()` function
when we increment buffLen (see
https://github.com/jgromes/RadioLib/blob/master/src/Module.cpp#L259).
By setting numBytes we incorrectly end up reading 2 bytes. Instead set
numBytes to zero so we only read the single status byte.
