Detect license hang for a long time

[iacore]

How to reproduce:

1. Create a new directory
2. Download https://gist.github.com/locriacyber/100837526561cc6b7f508868cfd33780 as LICENSE
3. zig init-exe
4. zigmod init

The process will hang for a long time.

I found the reason. Zig detect license gets the levenstein distance of the entire file (1KB).

pub fn detect(alloc: std.mem.Allocator, license_src: []const u8) ![]const u8 {
    var min: ?usize = null;
    var ind: ?usize = null;

    for (licenses.spdx) |item, i| {
        const distance = try leven.leven(u8, alloc, license_src, item[1], min);

        if (min == null or distance < min.?) {
            min = distance;
            ind = i;
        }
    }

    return licenses.spdx[ind.?][0];
}
