replace `_` by `-` in query parameter names?

[vincentsarago]

Right now we have a mix of both - and _ in query parameters names. I think it will be better to be coherent and use only one notation - (or _)

looking at https://www.terminusapp.com/blog/dash-or-underscore-in-urls/ it seems some people prefer using _ 🤷

_ parameters:

• colormap_name
• asset_indexes
• asset_as_band
• asset_expression
• max_size
• resampling_method
• return_mask
• histogram_bins
• histogram_range
• color_formula
• tile_format
• tile_scale
• pixel_selection (Mosaic)
• with_eo (STAC extension)
• with_raster (STAC extension)
• with_proj (STAC extension)
• asset_href (STAC extension)
• asset_media_type (STAC extension)
• asset_roles (STAC extension)
• asset_name (STAC extension)
• collection_url (STAC extension)

- parameters

• coord-crs
• dst-crs
• geom-densify-pts (STAC extension)
• geom-precision (STAC extension)

Let's hear your opinions!

While I love making breaking changes, I think we should keep all _ parameters and just changed the ones with -
