Do not validate Azure or GCP storage paths

 - `samplesheetToList()` now does dynamic typecasting instead of using the `type` fields in the JSON schema. This is done due to the complexity of `draft-2020-12` JSON schemas. This should not have that much impact but keep in mind that some types can be different between this version and older versions in nf-validation ([#141](https://github.com/nextflow-io/nf-validation/pull/141))
 - `samplesheetToList()` will now set all missing values as `[]` instead of the type specific defaults (because of the changes in the previous point). This should not change that much as this will also result in `false` when used in conditions. ([#141](https://github.com/nextflow-io/nf-validation/pull/141))
 - Removed the configuration parameters and added configuration options instead. For a full list of these new options, please have a look at the [configuration docs](https://nextflow-io.github.io/nf-schema/latest/configuration/)
+- Ignore validation of Azure and GCP hosted blob storage files in addition to AWS S3 hosted files. This is because they are not true POSIX compliant files and would incorrectly fail validation ([#29](https://github.com/nextflow-io/nf-schema/pull/29))
