mtlb_realmin - Matlab realmin emulation function

### Description

Scilab equivalent for Matlab `realmin` is `number_properties` but not all cases are implemented:

  - Scilab equivalent for Matlab `realmin` or `realmin('double')` is `number_properties("tiny")` .
  - There is no Scilab equivalent for Matlab `realmin('single')`

The function `mtlb_realmin(prec)` is used by `mfile2sci` to replace `realmin(prec)` when it was not possible to know what was the input while porting Matlab code to Scilab. This function will determine the correct semantic at run time. If you want to have a more efficient code it is possible to replace `mtlb_realmin` calls:

  - If `prec` is equal to `"double"` `mtlb_realmin(prec)` may be replaced by `number_properties("tiny")`

Caution: `mtlb_realmin` has not to be used for hand coded functions.
