PID stops with the same departure minute are omitted

[anlexcz]

In Prague PID data, Träwelling omits stops when two consecutive stops have the same displayed departure minute.

This happens repeatedly across different tram lines.

Example 1 – tram line 6:

• Kobylisy – 04:55
• Ke Stírce – 04:55

The PID source shows both stops, but Träwelling displays only Ke Stírce and omits Kobylisy.

The same happens later on the same trip:

• Výstaviště – 05:05
• Veletržní palác – 05:05

Träwelling displays only Veletržní palác.

Example 2 – tram line 12:
The original PID trip contains additional stops and platform-specific stops around Anděl and Malostranská, but Träwelling shows a shortened or incorrect stop sequence.

This issue occurs in many PID Prague trips, especially where two consecutive stop events have the same time at minute precision.

Expected behaviour:
All stops should be preserved in the correct stop_sequence, even when two consecutive stops have the same displayed HH:MM time.

Actual behaviour:
The earlier stop is omitted and only the later stop remains.

It looks like stops may be deduplicated by time instead of being kept according to stop_sequence.

Screenshots from Träwelling and the PID source are attached.
