new: [cve] automatic extraction of CVE id from commit message

If one of more CVE id(s) are found in a commit message, those are added
in the finding output.

Example:

  "8c6f86c7c5350fadf22d32d6cd4712e2ad4447ba": {
    "message": "Fix an overflow bug in rsaz_512_sqr\n\nThere is an overflow bug in the x64_64 Montgomery squaring procedure used in\nexponentiation with 512-bit moduli. No EC algorithms are affected. Analysis\nsuggests that attacks against 2-prime RSA1024, 3-prime RSA1536, and DSA1024 as a\nresult of this defect would be very difficult to perform and are not believed\nlikely. Attacks against DH512 are considered just feasible. However, for an\nattack the target would have to re-use the DH512 private key, which is not\nrecommended anyway. Also applications directly using the low level API\nBN_mod_exp may be affected if they use BN_FLG_CONSTTIME.\n\nCVE-2019-1551\n\nReviewed-by: Paul Dale <paul.dale@oracle.com>\nReviewed-by: Bernd Edlinger <bernd.edlinger@hotmail.de>\n(Merged from https://github.com/openssl/openssl/pull/10574)\n",

in the commit message.
