Add ability to parse position delimited files.

[xperiandri]

Is your feature request related to a problem? Please describe. I need to read a position delimited file (no delimiters)

Describe the solution you'd like Make TextFieldParser.cs types public

Describe alternatives you've considered Copy source code of TextFieldParser.cs

Instead of making the types public, a way to read a position delimited file would work as well, correct?

I've already created static methods to load such data to a DataFrame and I will publish that. However, you don't always want to use DataFrame. Sometimes you just want a reader that will put the result into a database as a record. I don't think that we need to read the whole document into memory.
