Tranquilo

This version contains several changes that improve the algorithm

- The parallel acceptance step now takes line-step points into account when creating a speculative sample and uses a smaller sampling radius (before we used the search radius for sampling by accident)
- The default target sample size for the noise-free and serial least-squares optimizer has been updated to p + 2 instead of p + 1. While this slows down tranquilo by a small factor it increases robustness.

- Remove direct dependencies on estimagic to avoid circular imports.

First version with adaptive noise handling and parallelization
