v0.2.0

Feature

• Serialization is supported with serde (see #13 by @LU15W1R7H).
• All Curves are now Sync.
• Better Tests against faulty inputs for BSplines (see #17).

Breaking Changes

• BSplineError contains different structs. This should make it clearer why the builder could not construct the wished for curve (see #14 ).
