This port of FastLED 3.3 runs under the 4.x ESP-IDF development environment. Enjoy.
HUGE UPDATE July 18, 2020. I have ported over Sam Guyer's branch, and now I can do network traffic
without having glitches. This is a MASSIVE IMPROVEMENT and you owe Sam huge props.
Note you must use the ESP-IDF environment, and the ESP-IDF build system. That's how the paths and whatnot are created.
Here is the link to the ESP-IDF getting started guide.

## SamGuyer's fork
According to a reddit post, someone named Sam Guyer fixed the issues with FastLED by using some async
mechanisms. This is still an arduino port, but maybe it's best to port this over next.
According to a reddit post, someone named Sam Guyer fixed the issues with FastLED. There are
a number of fundamental problems that Sam has been gnawing on, notably the access to flash
that happens when you 'read files'.
However, Sam found the truely important thing: that the built-in interrupt handler
wasn't working, because the use of templates obscured the IRAM_ATTR attribute. Which
means the "fast interrupt routing" to shovel bits into RMT was running out of executable
flash, not out of RAM, so of course it wouldn't keep up.

you're compiling all the other esp idf components, and you'll see a lot of stuff compile
then finally what you want.
The best way is to do a few builds - which will all fail, and the other components
without errors ( the ones in esp-idf )
will finally get built, then you'll be left with only your errors.
However, in recent versions of ESP-IDF, they've fixed a lot of things about the build system,
so we really shouldn't complain. Builds are now really fast, and `build` just builds what's not touched.
Building without `-j` parallelism would be nice, but I haven't found a way to do that. And, it would be slow.
Thanks, espressif!
