Coercion rules for Data::Sah

Data::Sah::Coerce contains a standard set of coercion rules for Data::Sah. It is separated from the Data-Sah distribution and can be used independently. A coercion rule is put in Data::Sah::Coerce::$COMPILER::To_$TARGET_TYPE::From_$SOURCE_TYPE::DESCRIPTION module, for example: Data::Sah::Coerce::perl::To_date::From_float::epoch for converting date from integer (Unix epoch) or Data::Sah::Coerce::perl::To_date::From_str::iso8601 for converting date from ISO8601 strings like "2016-05-15". Basically, a coercion rule will provide an expression (expr_match) that evaluates to true when data can be coerced, and an expression (expr_coerce) to actually coerce/convert data to the target type. This rule can be combined with other rules to form the final coercion code.
