LilcomChunkyWriter replaces storage_path if it contains "."

[chiiyeh]

Hi! I realize that when i use storage_path with . like "gigaspeech_overlap_0.3_TRAIN" it will end up becoming saving to the file "gigaspeech_overlap_0.lca" instead of "gigaspeech_overlap_0.3_TRAIN.lca" as expected.
It seems to be due to this line:

lhotse/lhotse/features/io.py

Line 829 in afc8eff

self.storage_path_ = Path(storage_path).with_suffix(".lca")

which replaces the words after "." with lca instead of appending.
I saw quite a few other places using .with_suffix as well so will have the same issue as well.

Good catch. We should probably change those to:

p = Path(storage_path)
self.storage_path_ = p.with_suffix(p.suffix + ".lca")
