requirements.txt pins ifcopenshell==0.7.0.240406 which is not available on PyPI

**Version:** 1.7.0
**Python:** 3.12
**OS:** Windows

**Problem:**
Installing compas_ifc via pip fails because `ifcopenshell==0.7.0.240406`
is not available on PyPI. Only versions >=0.7.10 are available.

**Error:**
ERROR: Could not find a version that satisfies the requirement
ifcopenshell==0.7.0.240406 (from compas-ifc)
(from versions: 0.7.10, 0.8.0, 0.8.1, 0.8.1.post1, 0.8.2, 0.8.3,
0.8.3.post1, 0.8.3.post2, 0.8.4, 0.8.4.post1, 0.8.5)

**Fix:**
Change requirements.txt from:
ifcopenshell==0.7.0.240406
to:
ifcopenshell>=0.8.4
