[esnacc-dev] [PATCH] cxx-lib/asn-buf: fix a large parameter pass-by-value

[Aaron Conole]

The BufferException object is quite large (>512 bytes), which incurrs
a performance impact.  Convert the pass-by-value to a
pass-by-reference.

Fixes: ea172d558054 ("cxx-lib/src/asn-buf: make GetSeg non-throwing.")
