Can't brace-initialize a BitSet with a std::string

[rodsan0]

Describe the bug
Brace-initializing a BitSet with a string results in a BitSet initialized to 1. This is because the initializer_list<T> ctor is preferred over the const std::string& one. The former ctor's type should be changed to initializer_list<bool> instead. Moreover, line 412 should ideally be commented out.

To Reproduce
Brace-initialize a BitSet with a std::string.

Expected behavior
BitSet contains a bit-for-bit representation of the contents of the "binary" std::string.

Toolchain (please complete the following information):

• OS: Arch Linux
• Compiler: Clang 13.0.0
• Empirical Version: native-canvas branch

Additional context
This bug is only present in the native-canvas branch.
