maturin develop doesn't include text color from rust build errors

[chaserileyroberts]

When using maturin develop, any rust error's that appear are just displayed in system default color text, making it slightly harder to read.

Vs when using say cargo build

• How is this important to you? How would you use it?
  Maybe a 3/10 importance. Certainly not a blocking issue, but it is a strong QOL issue.

• Can you think of any alternatives?
  Leaving it as is.

• Do you have any ideas about how it can be implemented? Are you willing/able to implement it? Do you need mentoring?
  Not sure why the coloring is missing, but I could figure it out I would be happy to open a PR.
