platform-dependent issue when deserializing an array with numbers outside `double` range

[carmichaelong]

The file attached is the normal gait2392 file but with one of the splines replaced with another spline to reproduce the error.

• Loading this file (using the GUI) in Windows is OK.
• Loading this file (using the GUI) in macOS throws an exception

Other notes:

• The lower bound for a double type is roughly 1e-308. Replacing the two numbers represented by scientific notation (i.e., 4.68444e-310 and 1.39067e-309) such that the exponent is within the acceptable range (i.e., e-307) allows the model to be loaded in macOS
• No differences in behavior between 4.3 and 4.4, so likely not a regression
