build ESP32-Duktape from source about duktape-esp32

[njacot]

So, I figured the issue.
I had to use the proper mkespfimage and mkspiffs.
I built mkespimage from here: https://github.com/Spritetm/libesphttpd/tree/master/espfs/mkespfsimage
and spiffs from here: https://github.com/igrr/mkspiffs/releases

Now I can build the all project and flash it to the esp32.

The access point web page works and I can connect the board to the local wifi.
The web IDE do not work for now. It is maybe an issue with the SPIFFS version since I took the latest one(0.2.3).

When I try to connect to the web IDE, I get this error:
D (58105) module_fs: - Path to open is "/spiffs/web/ide.html" and flags are "r" D (58115) module_fs: << js_fs_openSync fd: 3 D (58115) module_fs: >> js_fs_readSync D (58115) module_fs: Buffer pointer size returned as 128 D (58125) module_fs: js_fs_readSync: read() error: 5 I/O error

which seems to be the same issue as #24
so, this can be closed I think for now
