Add 8MB/16MB flash configs for Heltec Lora32/lilygo T-sim7000

The Problem is, that many boards have only 4MB Flash and I want to be comatible.
So I want to leave it to 4MB Flash.
As when I switch to esp v5.0.0 the Flash is completely full.
Maybe it works, when switching from PlatformIO (Arduino-IDE) to ESP-IDF
In ESP-IDF you can switch of components, which are not used and so you can safe flash-image-size.

What do you think about it ?

@gereic yes, but the change doesn't change anything for those boards? it just adds the option to have more features on larger boards. Like I'll implement wireguard for the larger boards. Wrapping that into ifdefs and enabling it only for the boards with more flash is possible.
I've kept the spiff/data size the same on all boards, so thats also compatible.

As far as I understand the esp-idf component thing, its the same as the libraries in pio. You can't disable the library dependency finder and handle them manually in pio, too - although in theory it should not include libraries that are not in use.

But what I think you might want to set is lib_ldf_mode = chain+ (default is chain, without +), so ifdefs are actually handled properly.

lib_ldf_mode = chain+ (or deep+) doesn't work as its not able to find the include of WiFi.h deeep in the websockets header. Not sure if there is a workaround except for managing the libs manually.

I think it will decrease the flash-size, when I unset Options for the small Boards (IPV6, BLuettoth Classic, CAN, ...)
Will Try it.

I'd expect that the parts might be built by pio, but not linked into the image.

Tricking the LDF into using the wifi module for websockets doesn't change the image size.
But a large part of the image seem to be debug information:
