lecp_parse() - parses a chunk of input CBOR
ctx: the parsing context cbor: the start of the chunk of CBOR len: the number of bytes of CBOR available at cbor
Returns LECP_CONTINUE if more input needed, one of enum lecp_reasons for a fatal error, else 0 for successful parsing completion.
On success or _CONTINUE, ctx->used_in is set to the number of input bytes consumed.

lecp_parse_report_raw() - turn cbor raw reporting on and off
- Parameters
-
| ctx | the lecp context |
| on | 0 to disable (defaults disabled), 1 to enable |
For cose_sign, it needs access to raw cbor subtrees for the hash input. This api causes LECPCB_LITERAL_CBOR parse callbacks when there are ctx->cbor_pos bytes of raw cbor available in ctx->cbor[]. the callbacks occur when the ctx->cbor[] buffer fills or if it holds anything when this spi is used to stop the reports.
The same CBOR that is being captured continues to be passed for parsing.
