Flexible send() return type

[raibis]

Hi,

I would like to use your abstract class from
https://github.com/starfederation/datastar-typescript/blob/main/src/abstractServerSentEventGenerator.ts

for my package https://www.npmjs.com/package/nestjs-datastar

Unfortunately, this is not possible because the send() method has a hard-coded return type of string[].

Could you please update the abstract class slightly by using generics, like this:

// ...
export abstract class ServerSentEventGenerator<T = string[]> {
// ...

  protected send(
    event: EventType,
    dataLines: string[],
    options: DatastarEventOptions,
  ): T {

This way, the return type of the send() method would be flexible.
