Specify custom local SOURCE

[blaylockbk]

If I have local grib files (I downloaded some with rclone) I'd like to tell herbie those exist without a custom template. Instead, I'd like to define the path in the "priority" argument.

Herbie(date, 
    model='hrrr', 
    priority=[
        ('local_rclone', "/path/to/{self.model}..."), #<-- provide the template here
        'aws',  
        'nomads'
    ]
