precompile failure on julia v1.4 when using with DifferentialEquations

[wnoise]

This failure is due to Julia 1.5 syntax used in the compatibility hook src/compat/diffeqbase.jl .

The Project.toml claims compatibility with Julia "1".

I do think compatibility with 1.4 is worth supporting, especially given that the current stable Ubuntu (20.04) comes with 1.4.1.

Pull request to follow (based off of the initial commit; my general policy is to create bug-fixes as far-back as practical so that it can most easily be merged into any branches that may have the bug.)

Demonstration and stack trace:
