fix: Don't ignore options.transforms for buble

[ntucker]

Motivation

Customizing transformer is not possible, which means disabling transforms like classes etc don't work. This is clearly a bug as it works in normal buble, and the options is spread in but not the options.transforms.

Additionally, we default to allowing classes and getter/setters as these are very useful features.

Test Plan

<LiveProvider
        transpileOptions={{
          target: { chrome: 71 },
          transforms: {
            classes: false,
            letConst: false,
            getterSetter: false,
            generator: false,
            asyncAwait: false,
            moduleImport: false,
            moduleExport: false,
          },
        }}
      >

Make sure it doesn't break on classes or getter setters

Can't figure out the prettier failure.... the format follows the rest of the file and the github action doesn't have any debug output.

This line clearly exceeds the length of 80 characters

Oops, should be:

  return transform(source, {
    ...options,
    transforms: {asyncAwait: false, ...options.transforms},
  });

in the latest Prettier version

LGTM thanks. I fixed the prettier issue, which unfortunately only show problematic files but no diff

Would love a release with this :D

We'll release soon, in the meantime you can use a canary release
