.NET Framework 4.8

[talley]

It does not work with .NET Framework 4.8

[barnhill]

The example application in this repo uses .NET Framework 4.8 ... is there something else you are seeing?

[WinoVeritas]

.NET Framework 4.8 project Compiler Error CS0234 "The type or namespace name "Barcode" does not exist in the namespace "BarcodeLib" (perhaps there is no reference to the assembly)."

[duploman]

Barcode exists only in BarcodeStandard, but Encode method has not the same signature.

[barnhill]

Looks like there is a need to do some namespace cleanup and get them all in BarcodeStandard. Ill fix this.

[barnhill]

This should be cleaned up with this PR: #203
