Case Sensitivity on row[string]

[Dreamwalker666]

Hi, @nietras

Been trying out the library and love it brilliant work.

One issue I have had was case of CSV file headers not matching the case when referencing the row key.

This isn't an issue on my test data but the files come from an external source and they can easily use the wrong case. So would it be possible to have an option to match case insensitive for the lookup?

Had been thinking about adding an option in SepReaderOptions for specifying StringComparer used in header dictionary, still have to check impact on rest of code. How does that sound?

I have done a little investigation and pushed a branch with a working change.

One problem I did have I couldn't find a way to test SepHeader.Parse directly as using Sep.New() I couldn't see a way to set the reader options?

It sounded like I was not clearly defining what I meant to change, I've created a work-in-progress PR for adding the relevant option in #113. I need to add tests, though.

Ah right got you.

I knew the change wouldn't be accurate I did, as I don't know the code base at all. I just wanted to do a little investigation work to help out. Passing it in does make more sense and why I had an issue trying to test it.

0.4.5 should be available on nuget, thanks for filling the issue.
