*
* LEJPCB_VAL_STR_START: We are starting to parse a string, no data yet
*
* LEJPCB_VAL_STR_CHUNK: We parsed LEJP_STRING_CHUNK -1 bytes of string data in
* ctx->buf, which is as much as we can buffer, so we are
* spilling it. If all your strings are less than
* LEJP_STRING_CHUNK - 1 bytes, you will never see this
* callback.
* LEJPCB_VAL_STR_CHUNK: We filled the string buffer in the ctx, but it's not
* the end of the string. We produce this to spill the
* intermediate buffer to the user code, so we can handle
* huge JSON strings using only the small buffer in the
* ctx. If the whole JSON string fits in the ctx buffer,
* you won't get these callbacks.
*
* LEJPCB_VAL_STR_END: String parsing has completed, the last chunk of the
* string is in ctx->buf.
