replaced original BLE_iBeacon.ino example with a known-good one

[Human]

Description of Change

I had no luck getting the original BLE_iBeacon.ino code to work as expected with iBeacon scanners, but the included reference code worked completely. Thanks to @31337Ghost for writing it! I am simply submitting the PR.

Tests scenarios

Tested on DOIT ESP32 DEVKIT V1, using various scanner client apps on Android devices.

Hi @Human, I am testing the example and can say, that this new one works better.
But I have a question, after disconnecting ESP from phones APP the ESP disappears and need to hw reset. Do you have same behaviour and is that correct?

Tested on ESP32 + ESP32-C3

@Human Can you please take a look on my comment above? Thanks

[Human]

@P-R-O-C-H-Y It will take me some time to be able to test this, but which app on which platform did you use?

@Human Please, it seems a lot of lines are still similar to the example created by Neil Kolban.

Can you please mentioned in the header that this example is "modified version by 31337Ghost User " of the original example from Neil?

Thanks

Please check revised comment.

@Human I did test on ESP32-C3 and with HONOR phone running Android 10 + app called nRF Connect (also tried another app, but got same behaviour).

@P-R-O-C-H-Y I tried your recommended app, and I do not get a CONNECT option for the ESP32 iBeacon running this code. I do see the option for a BlueCharm beacon and my TV (for some reason). (See update below.)

[Human]

@P-R-O-C-H-Y I was able to reproduce what you saw, but I don't know enough about BLE or iBeacons to fix the issue.

@Human please take a look on my comment :)

@Human could you please rebase this PR git rebase -i master because it seems to include some commits that are already on master and is causing CLA to think that there are many contributors.
