John Colvin fc1ae2e5cb Upgrade linux quickfix
WARNING: This is NOT an official release.  As of 12/10/21 20:23, the
latest release of the quickfix lib (1.15.1) does not support c++17
(the FIX::Application class has fns with dynamic exceptions).  This
commit upgrades to a more recent (unreleased) build which supports
c++17.
