dcc.Input has invalid attributes

[coleweusthem]

Following web standards all elements should use the format data-* when using unsupported attributes.

dcc.Input uses 'persisted_props' and 'persistence_type' as attributes, to comply with standards they should be 'data-persisted_props' and 'data-persistence_type'

<input id="lat_min" type="number" max="90" min="-90" placeholder="Min Latitude" step="5" persisted_props="value" persistence_type="local">
