Script: FlashFS and SD some issues

[nikito7]

Hardware:

• ESP32 C6 (maybe S3 too)
• Micro SD Card

Software version:

• self compiled:
  Program Version 14.2.0.3 (tasmota32)
  Build Date & Time 2024-08-27T20:32:13
  Core/SDK Version 3_0_4/5.1.4.240801

Issue 1:

res=fz(fr) overflows if file do not exist.
in esp8266 I used fz(fr) to check if file exist.

18:05:00.744 CSV: Headers LP-2024-08.csv **4278124288.00**
18:05:00.746 CSV: Updating LP-2024-08.csv 32.00
18:05:01.876 CFG: Saved, Count 410, Bytes 4096

The overflow it's random 4278124288.00

Issue 2:

UfsRun only run files from FlashFS

[gemu2015]

this checks if a file exists:
fx("fname") check if file fname exists

fz() returns the file size of an open file
you must check the value of fr=fo() (file open) before doing something with fr ( fr >= 0)

TFS is fixed to use flash file system only,

in scripter you may precede the path with
/ffs/ for flash file access
/sdfs/ for sd card access
default is flash if sd card not found, else sd card
