Migrating from Old library )est at lib) to this new lib (lwesp)

[Moo2017]

Hi @MaJerle
I've ported the old library and now I noticed that you have changed the library. I was wondering how difficult would be to migrate from the old one to this new one and could you please let me know what is the reason so change that? Is this new one more reliable and robust than the old version?

esp-at-lib has been renamed to lwesp first, to distinguish from esp-at library by Espressif. This has been done in the period of v0.xx releases where API may change.

The core architecture is the same and works at the same principle.
