Array support in ndjson input codec

[sivagnanam-arumugam]

Is your feature request related to a problem? Please describe.
ndjson input codec does not support json array line.
Example:
[{"key1":"value1"},{"key2":"value2"}] -> should be converted into three event objects
This case is handled in logstash ndjson input codec.

Describe the solution you'd like
When prepper reads from a source and the new line is a array string, then prepper should convert the array into n number of objects and publish it.

Describe alternatives you've considered (Optional)
A clear and concise description of any alternative solutions or features you've considered.

Additional context
nsjson input codec is working fine for json new line inputs, but not working for if the new line is an array of json objects.
{"key1":"value1"} : Working
[{"key1":"value1"},{"key2":"value2"}]: Not working

@sivagnanam-arumugam , This type of input should already be supported by the existing json codec. The only difference would be that it does not support multiple arrays.
