announcing under.c

`under' utility decodes binary DER data to S-expressions and/or encodes those back to DER.

Aren't you curious of how iteratees may look in C?

$ echo '(p1 (p2 "48 45 4c 4c 4f") (p3 ""))' | under -e | hexdump -C
00000000  e1 09 c2 05 48 45 4c 4c  4f c3 00                 |....HELLO..|
0000000b
$ ^hexdump -C^openssl asn1parse -inform DER -i
    0:d=0  hl=2 l=   9 cons: priv [ 1 ]        
    2:d=1  hl=2 l=   5 prim:  priv [ 2 ]        
    9:d=1  hl=2 l=   0 prim:  priv [ 3 ]
