Wintertoo

Major fix that affects only the API server, but not users.

What's Changed
* Set default date range at instantiation by robertdstein in https://github.com/winter-telescope/wintertoo/pull/68

**Full Changelog**: https://github.com/winter-telescope/wintertoo/compare/v1.5.0...v1.5.1

Adds option for Avros to be downloaded. Also renames `kind` to `image_type`, but maintains backwards-compatible alias.

What's Changed

This release renames some two core ToO API parameters:

* t_exp is now total_exposure_time
* n_exp is now n_repetitions

However, the old names are maintained as aliases, so the API will be backwards-compatible!

In addition: the release adds single_exposure_time, which is a calculated property equal to total_exposure_time/n_dithers. When ToOs are submitted, the calculated properties are ignored, but the user will see it if they e.g use print. We do pass singleExpTime in the .db files for convenience, but the scheduler will just ignore this.

The release also updates the default total exposure time to 960, and the default number of dithers to 8.

What's Changed
* Update with new ToO model by robertdstein in https://github.com/winter-telescope/wintertoo/pull/66


**Full Changelog**: https://github.com/winter-telescope/wintertoo/compare/v1.3.2...v1.4.0

Fixes a date bug where maximum value did not update over time.

What's Changed
* Swap to validation after initialisation by robertdstein in https://github.com/winter-telescope/wintertoo/pull/65


**Full Changelog**: https://github.com/winter-telescope/wintertoo/compare/v1.3.1...v1.3.2

Slightly updated model for image query. Adds one day grace period for requests covering the future, due to possible time zone confusion.

What's Changed
* Add one day grace on image querys being in future by robertdstein in https://github.com/winter-telescope/wintertoo/pull/64


**Full Changelog**: https://github.com/winter-telescope/wintertoo/compare/v1.3.0...v1.3.1

Somewhat breaking change: add bestDetector to schema, and options to ToO model etc to support that. It's a boolean to shift ra/dec to best detector.
