Merging into the Fiona project

[sgillies]

@tschaub what do you think about merging this project into Fiona? Then you all can close it up and have one less thing to look after.

Toblerity/Fiona#1327

Hi @sgillies - moving this code into Fiona makes sense to me. I'll ask around today to hear opinions from some others.

@sgillies - Moving this code to Fiona sounds good to others here. Under the current Apache license, Fiona would need to include the current copyright and license text. Would it be easier for Fiona to have us update the project to use The Unlicense or similar (so that Fiona didn't have to include the Planet copyright and Apache license going forward)?

@tschaub sure, the unlicense sounds good to me!
