# Updates barrel imports like:
#
#   import { CircularProgress, Stack, Typography } from '@mui/material';
#
# To individual direct imports:
#
#   import CircularProgress from '@mui/material/CircularProgress';
#   import Stack from '@mui/material/Stack';
#   import Typography from '@mui/material/Typography';
#
# We have this committed to a bin directory in a FE repo.
# The script is called from a husky pre-commit hook
