* Import Absolute Humidity component https://PigLab.ReaperLegion.net/home-automation/hass/esphome/custom-components/absolute-humidity * Fix terminology, add some docstrings * Switch from double to float https://github.com/esphome/esphome/pull/4519#pullrequestreview-1327615169 The additional precision doesn't matter in practice. * Address code review suggestions * Lint code
