wifi Config enhancement

[sekarpdkt]

I added an extension to allow user to configure various SSID list. If you are ok, will raise a PR. Basically, /wifi will bring the attached screenshot (page) and we can configure multiple SSIDs. Each SSID config is saved in a file. When SCAN happens, in addition to checking existing hardcoded list, it will also check for file availability. if file is found it is marked as available config. If best SSID is from file config, that file is used to connect to wifi. There are lots of changes in esp32-cam-webserver, app-httpd etc. Process:

1. Flash without any info.
2. Access Point is enabled
3. Connect to AP
4. Config Wifi info (by accessing /wifi (or click on new ICON added in main index page to access /wifi).
5. Save the config.
6. Reboot.
7. Cam will connect to new SSID. If IP address is given for that SSID, static IP is configured else DHCP IP is fetched.

If you feel it is aligned to your plan, will send a PR.

I would be quite interested in this feature... admittedly also for my own work. Do you have an AP/STA mode too?
I can't speak for the author, but I think this was something they were planning eventually (at least according to the readme).

Wrt AP/STA, trying to integrate it with esp_mesh(). (with out camera related load). And did some more enhancements like storing the wifi info in AES256 encrypted format... Actual key will be auto generated and stored in NVS, when we boot the cam first time. This week end will try to merge these two enhancement with webcam and if it works (memory:-) ).. will update here thru a fork...

@sekarpdkt : I am very interested in this; but not for the upcoming release; I do not want to be making any extensive changes at this point.
A PR would be welcome of course, once 4.0 is out it can be rebased and I can go for a rapid v4.1 to implement it once tested and ready.
Somehow incorporating mesh networking would be nice, it is a good feature for this sort of device.

I was wondering if I could download the add-on?
