support to return all possible java homes instead of one

[Eskibear]

Now it searches and returns the first one. Can we add options like {all: boolean} to return all possible candidates?

@Eskibear i think it may be a better interface to also export findJavaHomes

[Eskibear]

Then I'll try creating a PR to add something like

export async function findJavaHome(options): Promise<string>
export async function findJavaHomes(options): Promise<string[]>

[Eskibear]

I tried but was not able to also export findJavaHomes(options) while keeping backward compatibility, i.e.

require('find-java-home')(function(err, home){
  if(err)return console.log(err);
  console.log(home);
});

We can export a namespace containing both APIs by default, then you have to specify which one to use, and above code should become

const apis = require('find-java-home');
apis.findJavaHome(function(err, home){
  if(err)return console.log(err);
  console.log(home);
})

yea, i was thinking of a named export for findJavaHomes too 👍
