bug(cksum): panics when using an algorithm shake128 and shake256 with an extremly large length

[HackingRepo]

Hi, uutils mainteners

i see chksum panics when using

relunsec@relunsec:~/software/coreutils/target/debug$ ./cksum -l=10011111117721172727 --algorithm shake128 a
memory allocation of 1251388889715146591 bytes failed
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Aborted                    (core dumped) ./cksum -l=10011111117721172727 --algorithm shake128 a
relunsec@relunsec:~/software/coreutils/target/debug$ 

or

relunsec@relunsec:~/software/coreutils/target/debug$ ./cksum -l=10011111117721172727 --algorithm shake256 a
memory allocation of 1251388889715146591 bytes failed
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
Aborted                    (core dumped) ./cksum -l=10011111117721172727 --algorithm shake256 a
relunsec@relunsec:~/software/coreutils/target/debug$ 

note: that cannot be reproduced in gnu one because shake128 and shake256 only supported by the rust version
