Simple C lib of the MD5 & TEA algorithm

Performance

Benchmark a 3.5MB file comparing with md5 command in MacOS Mojave by running three times time command then calculating their average.

# system command: total 22ms
real    0m0.015s
user    0m0.012s
sys     0m0.005s

# our md5 command: total 39ms
# build by
gcc md5.c -o md5 -O3 -DTEST_SIMPLE_CRYPTO

real    0m0.021s
user    0m0.013s
sys     0m0.005s

Our version is 17ms slower than what system does.

Benchmark a 481.7MB file comparing with md5 command in MacOS Mojave by running three times time command then calculating their average.

# system command: total 2079ms
real    0m0.980s
user    0m0.964s
sys     0m0.135s

# our md5 command: total 2499ms
# build by
gcc md5.c -o md5 -O3 -DTEST_SIMPLE_CRYPTO

real    0m1.253s
user    0m1.003s
sys     0m0.243s

Our version is 400ms slower than what system does.
