GQL: Search txs for blocks range

[herr-seppia]

Describe what you want implemented
Add a blocksrange filter to lookup transaction (similar to the range filter for blocks lookup)
e.g.:

{
  transactions(blocksrange: [0,1000]) {
      blockheight
      blocktimestamp
      gasspent
      json
      txerror
      txid
  }
}

Describe "Why" this is needed
In order to retrieve transaction directly without requesting the blocks

Describe alternatives you've considered
Atm the same result can be achieved querying the blocks for a specific range and then request the transactions for those blocks

{
  blocks(range: [0,1000]) {
    header {
      height
      timestamp
    }
    transactions {
      gasspent
      json
      txerror
      txid
    }
  } 
}

However, this is a waste of bandwidth, because this returns information even for blocks that doesn't have transaction
