KCL's `fillet` function takes an array of edges to fillet. Previously this would do `n` fillet API commands, one per edge. This PR combines them all into one call, which should improve performance. You can see the effect in the artifact_commands snapshots, e.g. `rust/kcl-lib/tests/kcl_samples/axial-fan/artifact_commands.snap`
Besides performance, this should fix a bug where some KCL fillets would fail, when they should have succeeded. Example from @max-mrgrsk:
```kcl
sketch001 = startSketchOn(XY)
|> startProfile(at = [-12, -6])
|> line(end = [0, 12], tag = $seg04)
|> line(end = [24, 0], tag = $seg03)
|> line(end = [0, -12], tag = $seg02)
|> line(endAbsolute = [profileStartX(%), profileStartY(%)], tag = $seg01)
|> close()
extrude001 = extrude(
sketch001,
length = 12,
tagEnd = $capEnd001,
tagStart = $capStart001,
)
|> fillet(
radius = 5,
tags = [
getCommonEdge(faces = [seg02, capEnd001]),
getCommonEdge(faces = [seg01, capEnd001]),
getCommonEdge(faces = [seg03, capEnd001]),
getCommonEdge(faces = [seg04, capEnd001])
],
)
```
This program fails on main, but succeeds on this branch.
