Encoding and Decoding case insensitive enums

[AbhigyaKrishna]

Implemented case-insensitive enumeration encoding and decoding.

Changelogs

• Configuration value for decodeEnumCaseInsensitive defaults to false.
• Implementation of lenient deserialization in enum decoder.
• Emits lowercase enum names when configured to true for consistency with Json format.
• Implemented tests for case insensitive enums deserialization.

enum class TestEnum {
    VALUE
}

val yaml = Yaml(configuration = YamlConfiguration(decodeEnumCaseInsensitive = true))

val inResult = yaml.encodeToString(TestEnum.VALUE) // Outputs: value
val outResult = yaml.decodeFromString<TestEnum>("value") // Outputs: TestEnum.VALUE

I need this as well. We switched from json files to yaml but are missing case-insensitive enum deserialization that the kotlinx serialization library has. Would love to see this merged soon if possible!

note: I think if we don't change the encoding we should revert the code to the original state

[AbhigyaKrishna]

Its the same code, rather descriptive.

Thanks for the PR!

I don't think there's a need to mark this as experimental.

[AbhigyaKrishna]

All the new api features are marked as experimental in the kotlinx.serialization library when they are introduced. As a matter of fact, its their convention.

Thanks again for the PR!
