Shrine.cr Versions Save

Updated S3 upload mechanics.

Updated dependencies. Fixed supported Crystal versions.

The StoreDimensions plugin extracts dimensions of uploaded images and stores them into the metadata.

class Uploader < Shrine
  load_plugin(Shrine::Plugins::StoreDimensions,
    analyzer: Shrine::Plugins::StoreDimensions::Tools::BuiltIn)

  finalize_plugins!
end

image.metadata["width"]
image.metadata["height"]

Removed JSON.mapping in favor of JSON::Serializable. Thanks to @wout.

Added support for S3 Storage.

Shrine.cr got plugin system! Hooray!

Two plugins (DetermineMimeType and AddMetadata) are are included into this shard, you can read more about them in Readme.

Also I refactored Shrine::UploadedFile::Metadata into Shrine::UploadedFile::MetadataType which is now a Hash. NamedTuple are also replaced with Hash in Shrine and Shrine::UploadedFile classes.
