* Remove duplicated sha1 implementation (Fixes #6568) The Hash library had its own copy of a loop-unrolled sha1 implementation adding a large code footprint for no good reason, as there are several sha1 implementations already in tree (one in NONOS-SDK as well as one in bearssl). Switching to the bearssl one is straightforward and removes about 3kb of code size overhead. Also cleanup some obvious inefficiencies (copy by value, string summing, no reservation causing repeated reallocations) in the implementation. * Remove overload variants for sha1(...) that accept nonconst data The data is always remaining unmodified, so non-const overloads are confusing and redundant. Also optimize the hexify variant a bit more.
