Litebird-sim

- **Breaking change** The wrapper to the TOAST2 mapmaker has been fixed, and the parameter `baseline_length` was renamed to `baseline_length_s` to make clear what the measurement unit is [182](https://github.com/litebird/litebird_sim/pull/182)

- **Breaking change** New API for noise module [151](https://github.com/litebird/litebird_sim/pull/151):

- Function `add_noise` has been renamed to `add_noise_to_observations`, and its parameter `noisetype` has been renamed into `noise_type` for consistency with other parameters (**breaking**)

- New functions `add_white_noise` and `add_one_over_f_noise` are exported (they were already implemented but were not visible)

- Each `Simulation` object creates random number generators (field `Simulation.random`), in a way that is safe even for MPI applications

- **Breaking change** New API for `scan_map_in_observations` and `add_dipole_to_observations`, which now accept list of pointing matrices and simplify the parameters describing the HWP [171](https://github.com/litebird/litebird_sim/pull/171)
