Accept array-like time inputs in rv

[sylvesterkaczmarek]

Summary

Accept normal Python list and tuple values for the documented array_like time argument in ssapy.compute.rv().

Problem

_countTime() leaves iterable inputs unchanged. rv() then passes them to HashableArrayContainer, which expects a NumPy array and accesses .flags.writeable. As a result, a Python list raises AttributeError before propagation.

Change

• Convert non-scalar iterable time inputs to np.asarray() in _countTime().
• Preserve the existing scalar squeezing behaviour.
• Add regression coverage showing list and tuple inputs match ndarray results.

Validation

• python3 -m compileall -q ssapy/compute.py tests/test_orbit.py
• git diff --check

The local default Python environment does not have pytest installed, so the focused pytest case was not run locally.

Fixes #137
