[ktf]

This abstract the reading of I/O files from TFile, and introduces a new
plugin which is able to read them without using ROOT at all. The goal of this
is to demonstrate:

• reduced dependency on ROOT for I/O, getting rid of the interpreter overhead
• optimise access patterns based on the known AO2D structure, reducing the number of stats
• reduce memory usage by decompressing stream on the fly, rather than going through multiple tbuffers
• parallel decompression of baskets
• prefetching of dataframes
• support for https without depending of webdav libraries
