Feature request: Custom deliminator

[pbsds]

a possible use case could be to filter nested class names or attributes, i.e. strings on the form foo.bar.baz.

Would you consider adding support for configuring the deliminator?

Yep! I can add this to the next release.

I've actually had support for arbitrary delimiters in the code since the beginning, I just haven't exposed it as a flag yet.

zf/src/filter.zig

Lines 14 to 22 in 6624df5

	/// read the candidates from the buffer
	pub fn collectCandidates(allocator: std.mem.Allocator, buf: []const u8, delimiter: u8) ![][]const u8 {
	var candidates = ArrayList([]const u8).init(allocator);
	// find delimiters
	var start: usize = 0;
	for (buf) |char, index| {
	if (char == delimiter) {
	// add to arraylist only if slice is not all delimiters

I expect there would only be a need for single byte delimiters.
