add support for esp32s3

[offspring]

Verified using
esp32-s3-tiny
esp32-s3-dev-kit-n8r8
sn65hvd230-can-board

Sorry Timo i have to recreate #28 from fork / branch so it is easier to use from Platform io as https://github.com/offspring/NMEA2000_esp32.git#add-esp32s3 in lib deps section

So, to try this out, all I have to do is edit the platformio.ini file, as you mention above? Thanks.

You may need a board definition platformio_boards

[offspring]

and platform.ini

[env]
platform = espressif32
framework = arduino

lib_deps =
  ttlappalainen/NMEA2000-library
  https://github.com/offspring/NMEA2000_esp32.git#add-esp32s3

[env:esp32-s3-fh4r2]
board = esp32-s3-fh4r2

[env:esp32-s3-dev-kit-n8r8]
board = esp32-s3-dev-kit-n8r8

This may be problematic:
#if ARDUINO >= 100
#include <Arduino.h>
#endif

If one does not use arduino environment, it will fail. Do you really need to include Arduino.h?

[offspring]

#if ARDUINO >= 100
#include <Arduino.h>
#endif

No Arduino no issue that is why you have a guard

#if ARDUINO >= 100
#include <Arduino.h>
#endif

And all changes are guarded by specific defines too. it will be possible to do similar defines for non Arduino systems

Some newbies, like me, may find this quick note useful.

The following compiles clean using my custom dev board, from simple platformio/pio command line ubuntu dev env:

pio command

$ /usr/bin/pio run --environment base

platform.io file:

[env:base]
platform = espressif32
framework = arduino
board = esp32-s3-devkitc-1
monitor_speed = 115200
lib_deps =
  https://github.com/ttlappalainen/NMEA2000
  https://github.com/offspring/NMEA2000_esp32

Of course with valid src files. See pio project --help

TODO:
Will connect esp32s3 to my known to work well n2k interface (ISO1050 w/filter and static protection diodes) and will get back with results.
