* Rebaseline firmware to non-OS SDK version 3.0
* Note that SDK version 3.0 introduces the concept of a Flash Partition Table(PT). This is located at Flash offset 0x10000 in our firmware build.
* The firmware is now PT aware with both LFS and SPIFFS taking their partition size and location from the PT
* A new tool `tools/nodemcu-partition.py` is now used to initialise these data and can also download LFS and SPIFFS images to these partitions.
Fixes#1164 and thus also #1150, #1149, #1147 and #898.
* Move to latest version of SPIFFS
* Add SPIFFS porting layer for NodeMCU
* Add option to delete output if it doesn't fit
* Change FLASHSIZE to be in bits by default: default 4mb 32mb
* Add SPIFFS_MAX_FILESYSTEM_SIZE override
* Add notes on SPIFFS_FIXED_LOCATION
* Add 1M boundary
* Include the current version of the LICENSE
