exclude chrono default-features

[robjtede]

in an effort to remove time v0.1 from the dep graph

@robjtede, hello! Can you explane, what you want?

[robjtede]

cargo audit compains about vulnerabilities in time v0.1 which is enabled transitively via chrono when the oldtime feature is enabled. This PR disables that feature of chrono since it's very unlikely that sea-query relies on the feature.

[robjtede]

I would suggest pinning the version to ^0.4 insead of ^0

yep so would I but i've left them all as they were since it's not the purpose of this PR

(I'd also suggest not using ^ in the version reqs, but... as above...)

Oh... sorry I thought it was ^0.4 but in fact it's originally ^0
