Excessive memory use loading large yaml stream?

[Bascy]

I've added some logging of freeheap to the whole parsing process and this is what I found:

To load the test document from the deserialize.ino example, which contains 6 properties, total length 91 characters, at its peak (after calling yaml_parser_load_nodes in loader.c) the parser has reduced freeheap with 7216 bytes. The resulting json document is 127 bytes

To load my document (397 properties, 9277 bytes) at the peak the parser has reduced freeheap with 129420 bytes. The resulting Json document is 9020 bytes

I don't think this is ever going to work with large applications running on i.e. a ESP32 board ...

Or am I doing something wrong and is it possible to have the parser create the Json document in parallel with reading the yaml file, so it doesnt need to create a huge node tree in memory before calls deserializeYml_JsonObject() ?

I created my own Builder imlementation that creates the json document without using soo much memory, so this issue can be closed
