"task binding" without hardcoded file suffixes about bionode-watermill HOT 1 OPEN

Some ideas to solve this might be:

• to allow for several inputs with the same pattern *.foo.

{ input: [ { pattern: '*.foo', multiple: true } ]

However this wouldn't be able to match certain tasks. This is somewhat related to #65 .

• to reference other tasks within a task definition of the input:

{ input: [ { pattern: '*.foo', tasksNames: [ task1, task2, ... ] } ] } 
// this taskNames would take the name of the tasks in an array for watermill 
// to search for the resolvedOutput in their respective tasks

Then on its execution it would be a function similar to the one that follows:

({ inTasks }) => `countsnps ${inTasks.map(obj => obj.output).join(' ')}`

• Or maybe a mixture of the two previous options?
