This commit adds the new interface IOStreamConfigurationStore that provides two
new methods, one for reading configurations from InputStreams and a second
for writing configurations to OutputStreams. This interfaces is implemented
by the YamlConfigurationStore class.
* Windows Test Support - Add helper methods to convert the unix absolute path to the Jimfs's supported Windows path
* Windows Test Support - Bump Jimfs version
* Windows Test Support - Implement helper methods to the needed paths
* Windows Test Support - Implement helper methods to the needed paths and remove the unsupported (on Windows) newline character in the filename
* Windows Test Support - Statically importing the helper methods
* Windows Test Support - Statically importing the helper methods and changing the constant field names to good practices
**Support for polymorphic serialization**
This release adds the Polymorphic and PolymorphicTypes annotations that
can be used on types. Serializers for polymorphic types are not
selected based on the compile-time types of configuration elements, but
instead are chosen at runtime based on the actual types of their values.
This enables adding instances of subclasses / implementations of a
polymorphic type to collections.
**Add SerializeWith annotation**
This annotation enforces the use of the specified serializer for a
configuration element or type. It can be applied to configuration
elements (i.e. class fields and record components), to types, and to
other annotations.
**Add SerializerContext interface**
Instances of this interface contain information about the context in which
a serializer was selected. They are passed to the constructors of custom
serializers if the serializers are instantiated by this library, or can
alternatively be accessed through the new `addSerializerFactory` method
of `ConfigurationProperties` objects.

This update contains several new features:
* Support for Java records
* Support for File, Path, URL, URI, Instant
* New project structure that makes it easier to add support
for additional file types
... and some breaking changes:
* The code for saving and loading YAML files was moved from the
configlib-core to the configlib-yaml module:
* The Configurations class has been renamed to YamlConfigurations
and its methods lost their -YamlConfiguration affix.
* FieldFormatter has been renamed to NameFormatter
This annotation can be used to apply a FieldNameFormatter
to a Configuration without having to instantiate a Properties
object. The FieldNameFormatter returned by the annotation
takes precedence over the value returned by the Properties object.
Added FieldNameFormatters.UPPER_UNDERSCORE
If your configuration has a lot of fields and you want to exclude some
of these fields without making them final, static or transient, you can
configure your properties object to use additional FieldFilters.
A FieldFilter filters the fields of a configuration class by a specified
criterion. For example, if you only want to include fields whose names
don't start with 'ignore', you would add the following filter:
YamlProperties properties = YamlProperties.builder()
.addFilter(field -> !field.getName().startsWith("ignore"))
// ...
.build();
