v0.2.0

Breaking changes:

• Rename MBRGenerationConfig to MBRConfig
• MetricRunner now returns a MetricOutput dict instead of the raw tensor of scores.

New features:

• Make the size of the metric cache configurable via MBRConfig.metric_cache_size
• Allow that the number of references can be larger than the number of samples (if generated separately from the samples)

Other changes:

• Remove GenerationConfig as parent class of MBRConfig
• Use FIFO cache instead of LRU for metric cache
• Extend caching to CometMetricRunner
