Using LittleFS with ESP32 but app still with SPIFFS+LittleFS #472

Hello,
I've converted my main ESP32 app to use LittleFS instead of SPIFFS, which is working great. But I still see SPIFFS being compiled in the dependency tree due to AutoConnect and Pagebuilder:

-- <LittleFS_esp32> 1.0.6
|   |-- <FS> 1.0
|-- <AutoConnect> 1.3.3
|   |-- <PageBuilder> 1.5.2
|   |   |-- <FS> 1.0
|   |   |-- <LittleFS_esp32> 1.0.6
|   |   |   |-- <FS> 1.0
|   |   |-- <SPIFFS> 1.0
|   |   |   |-- <FS> 1.0
|   |   |-- <WebServer> 1.0
|   |   |   |-- <WiFi> 1.0
|   |   |   |-- <FS> 1.0
|   |   |-- <WiFi> 1.0
|   |-- <ArduinoJson> 6.19.2
|   |-- <DNSServer> 1.1.0
|   |   |-- <WiFi> 1.0
|   |-- <EEPROM> 1.0.3
|   |-- <WebServer> 1.0
|   |   |-- <WiFi> 1.0
|   |   |-- <FS> 1.0
|   |-- <WiFi> 1.0
|   |-- <Preferences> 1.0
|   |-- <LittleFS_esp32> 1.0.6
|   |   |-- <FS> 1.0
|   |-- <FS> 1.0
|   |-- <SPIFFS> 1.0
|   |   |-- <FS> 1.0
|   |-- <Update> 1.0
|   |-- <Ticker> 1.1
|   |-- <HTTPClient> 1.2
|   |   |-- <WiFi> 1.0
|   |   |-- <WiFiClientSecure> 1.0
|   |   |   |-- <WiFi> 1.0
|   |-- <HTTPUpdate> 1.3
|   |   |-- <HTTPClient> 1.2
|   |   |   |-- <WiFi> 1.0
|   |   |   |-- <WiFiClientSecure> 1.0
|   |   |   |   |-- <WiFi> 1.0
|   |   |-- <Update> 1.0
|   |   |-- <WiFi> 1.0
|   |-- <SD(esp32)> 1.0.5
|   |   |-- <FS> 1.0
|   |   |-- <SPI> 1.0
|   |-- <SPI> 1.0
|-- <SD_MMC> 1.0
|   |-- <FS> 1.0
|-- <NimBLE-Arduino> 1.3.7
|-- <Preferences> 1.0
|-- <ESP8266 and ESP32 OLED driver for SSD1306 displays> 4.2.1
|   |-- <SPI> 1.0
|   |-- <Wire> 1.0.1

The code compiles clean and runs great, even with both SPIFFS and LITTLEFS in the tree. I'd like to figure out how to not have SPIFFS compiled into the code, hopefully freeing up some code and stack memory. For the record, I am not using any of the Autoconnect features of uploading files or custom web pages that actually need to write to the local FS.

I've read this entire page: https://hieromon.github.io/AutoConnect/filesystem.html#selecting-appropriate-filesystem and I've added this to my platformio.ini file:

board_build.filesystem = littlefs   ; was already there
lib_ldf_mode=deep
build_flags =
    -DAC_USE_LITTLEFS
    -DPB_USE_LITTLEFS

But when I do that, I get a long list of compile errors (see below). I've search and search and tried everything I could find, but can't figure out how to get this to compile with only LITTLEFS. I'm sure it's probably one little thing that's triggering all these errors, but I sure can't figure it out. Help me Hieromon, you're my only hope!

Thank you, and thank you for your awesome library!

How to avoid the problem for now:

You will need to employ one of the following two methods. The following workarounds have their limitations. Those limitations will be lifted in the next release as AutoConnect v1.3.4 and PageBuilder v 1.5.3.

Modify the AutoConnectFS.h and PageBuilder.h

If you apply this fix, you will not be able to build sketches with the ESP32 Core 2.0 component or ESP8266 Core applied in the Arudino IDE. This will cause a compile error.

Change to:
```
#define PB_APPLIED_FILECLASS              fs::LITTLEFSFS
```
Modify the LITTLEFS.h, LITTLEFS.cpp in LittleFS_esp32 library source

If you apply this fix, you will no longer be able to build your legacy sketches with the LittleFS_esp32 library applied. This will cause a compile error.
