ppo

This module contains functionality to download data from the Plant Phenology Ontology data portal.

Uses rppo to get data from http://plantphenology.org/

Example:

```python
from springtime.datasets.ppo import RPPO
dataset = RPPO(
    genus="Quercus Pinus",
    termID="obo:PPO_0002313",
    limit=10,
    years=[2019, 2020],
    area=dict(name="somewhere", bbox=[-83, 27,-82, 28])
)
dataset.download()
df = dataset.load()
df
```

`RPPO`

Bases: Dataset

Download and load PPO data.

Attributes:

Name	Type	Description
`years`		timerange. For example years=[2000, 2002] downloads data for three years.
`genus`	`str`	plant genus, e.g. "Quercus". See PPO documentation.
`termID`	`str`	plant development stage, e.g. "obo:PPO_0002313" means "true leaves present". See PPO documentation.
`area`	`Optional[NamedArea]`	A dictionary of the form `{"name": "yourname", "bbox": [xmin, ymin, xmax, ymax]}`.
`limit`	`Optional[PositiveInt]`	Maximum number of records to retreive
`timeLimit`	`PositiveInt`	Number of seconds to wait for the server to respond
`exclude_terms`	`list[str]`	termIDs to exclude from the results
`infer_event`	`None \| Literal['first_yes_day', 'last_yes_day']`	whether to keep all (state-based) observations or infer the phenological event by setting it to "first_yes_day" or "last_yes_day".
