Download data at point of interest or at a given radius around point

[AdrienWehrle]

At the moment, a bounding box must be given by user to download data. Some users expressed the wish to download data at a given point and its surroundings, which then requires to compute the coordinates at a given distance around the point of interest.

This could be implemented in earthspy by downloading given bounding_box a list of two values (corresponding to the coordinates of a point) instead of 4 (the 4 coordinates of the bounding box) and a new optional argument for the distance around point. If distance equals 0 (default), only return the very pixel.

Use shb.to_utm_bbox with coordinate duplicates, then add/subtract distance in meters if radius is given

For radius = 0, better download an image that's a big bigger than the point of interest and extract data at point using rasterio's methods, and return locally + write as csv
