fix(ui-color-picker,ui-color-utils): fix corrupted CJS build

babel-plugin-transform-imports cannot handle if there are multiple exports from a file. This commit
adds a default export which works with this plugin
TEST PLAN:
make sure the CJS builds do not try to run function from color utils without importing them
