Analysis engine: adaptive step scanner might create a bad duration

[ChristopherRabotin]

Bug report

Hifitime 4.3.0 introduced additional checks when creating epochs and when creating durations from time units.

Describe the bug

The analysis engine might encounter this runtime assertion:

        assert!(
            q.is_finite(),
            "Attempted to create a Duration from a non-finite number"
        );

thread 'main' (461898) panicked at /home/chris/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/hifitime-4.3.0/src/timeunits.rs:305:9:
Attempted to create a Duration from a non-finite number
stack backtrace:

   3: anise::analysis::utils::adaptive_step_scanner
   4: anise::analysis::search::<impl anise::almanac::Almanac>::report_event_arcs
(...)

To Reproduce

Unsure yet... Note that this bug happens without changing any code that was not panicking with hifitime 4.2.6.

Expected behavior

Durations should all be finite!
