Added scipy to requirements.txt

Added scipy to requirements.txt as it is used but not added to requirements

This breaks the conditional importing of bitsandbytes, i.e.,

try:
    import bitsandbytes

    has_bitsandbytes = True
except ImportError:
    bitsandbytes = None  # type: ignore
    has_bitsandbytes = False

has_bitsandbytes will be False even if the user has the library installed (but not scipy) since the ImportError gets masked.

EDIT: According to the official docs, the requirement should also be added to install_requires.

I think that the dependency should also be added to the install_requires, otherwise scipy doesn't get installed when pip install-ing bitsandbytes.

@TimDettmers
Could we merge it?
Apparently 8a20cd8 is not enough.

Should be a quick merge in case this got forgotten 😅

@TimDettmers is this ok to merge?

8a20cd8 is indeed not enough. Anyone installing bitsandbytes through pip e.g. pip install bitsandbytes will not install scipy and code will error.
scipy needs to be added to the install_requires

This still needs to be addressed. Easy fix, should be merged
