Allow custom dtype for some VSA similarity functions #160

Closed mikeheddes closed 1 year ago

Description

With this PR a dtype can be specified for the return of the MAPTensor, BSBCTensor, and BSCTensor. The computation of the similarity value is also performed in this dtype. One therefore has to be careful not to make the precision too low to avoid overflows. This PR closes #158 .
