BrowserConfig Interface - Incorrect Required Property

[matdombrock]

The BrowserConfig interface requires type but I don't think that's really meant to be required. The README says that all options are optional.

bonjour-service/src/lib/browser.ts

Line 15 in 67ed22f

type : string

This should be changed to:

export interface BrowserConfig {
    type?        : string // now optional
    name?       : string
    protocol?   : 'tcp' | 'udp'
    subtypes?   : string[]
    txt?        : KeyValue
}

Making this change myself gives me the expected behavior, which is looking for all service types.
