Fixing the contiguous memory allocation bug with dragonfly router sampling, sampling struct had two dynamic arrays so a contiguous fwrite wasn't working

(i) Adding sampling for dragonfly compute node LPs (ii) Adding file I/O reader that translates the binary format to text

NOTE: no models implement it yet

(i) more text on how to run dragonfly with network traces (ii) some stat reporting fixes with dragonfly (iii) modifying config file error handling for dragonfly/torus (iv) modified dragonfly reverse handler for out of order packet handling, now it deletes the hash entry that it created in forward mode
