Multiple warnings on MVSC 2022

[izonfreak]

There are multiple warnings when compiling the project. I see that there are some sanity checks that verify that the values are in range. A lot of them are conversion errors (lost of data). I see that there are some sanity checks that verify that the values are in range. There are also some warnings in which "const" seems to be thrown away. (e.g., CipEpathSetLogicalValue)
