Fixed wrong data types for several UART config items.

[MichaelEFlip]

Using the wrong data type seems to load the default value instead of the stored value in NVS. The stored value in the web interface is instead displayed correctly as loaded through a different mechanism.

How did you do it? Even from pre release bins pin assigment doesn't work

[MichaelEFlip]

You have to create a own binary / compile latest version including this pull request. Otherwise assignment of custom pins does not work.

That is where I'm struggling to get my head around. I'm trying to do it with esp edf5.1, it gives errors
Which version of esp idf you used? I tried several but getting error after error...

update: finally I found version that works ESP-IDF 4.1.
I made a fork from your repository.
