Delay-and-error profile to frame-erasure pattern conversion tool. Reads a
delay/error profile (one entry per packet, giving network delay in ms and a
loss flag) and emits an error pattern suitable for use with the STL
eid-xor tool. Supports both fixed-delay and bounded-loss-rate jitter
buffer management emulation modes.

Provided by Fraunhofer IIS via 3GPP Tdoc S4-121077, in support of the EVS
codec processing plan.

Thank you very much for the contribution. Could you provide test vectors to ensure the compiled software works as intended?

@sdoehla-iis, does the tool actually produce a g192 compatible bitstream as in src/eid/gen-patt.c for example?
I thought g192 patterns were a binary stream, but the current tool writes the stream in text mode. This can cause issues.
