feat(core): Updated all core version to 16407d55

This wastes a vast amount of precious IRAM memory and also it tends to crash frequently, in SDK code itself (not my code) with an LoadStoreException.

I really like the previous version "feat(core): update net802.11 version to 5d71a456" where the amount of used IRAM was minimal and there were no issues that bothered me.

Have you tried the latest commit? I lose about 1.3 kB of heap.

I took a close look and compared the .a files. None were suspicious except for one. Part of libmain.a ended up in my crosshairs. These are the sizes of the sections inside libmain.a(app_main.o), comparing the old working to the new commit:

.xtensa.info:                       old:440   new:56

To obtain the info
xtensa-lx106-elf-objdump -s
was used.

Some sections vanished in the new commit, some became smaller, some slightly bigger.
.text.user_start and .text.user_fatal_exception_handler became way bigger.
I don't know what it means and if anything can be done about it. But overall, the change in size reflects the shrunken amount of free heap.
