otf_api is too strict about version comparison

[aschw]

Line 114 of IrDecoder.h reads:

if (token.signal() == Signal::BEGIN_MESSAGE && token.fieldId() == id && token.tokenVersion() == version)

I haven't traced out the path from xml to sbeir to cpp, but I'm pretty sure that token.tokenVersion() comes from the XML's sinceVersion field. If so, a strict version match is not appropriate. I think the version check should be changed to an inequality.

if (token.signal() == Signal::BEGIN_MESSAGE && token.fieldId() == id && token.tokenVersion() <= version)

Thanks.
