getBlockRange() returns an error for range of 1.

[ehamery]

The getBlockRange method returns an error for valid input:

tronweb/src/lib/trx.js

Lines 516 to 517 in 4b131bb

	if (!utils.isInteger(end) || end <= start)
	return callback('Invalid end of range provided');

It should be < instead of <=:

if (!utils.isInteger(end) || end < start)
    return callback('Invalid end of range provided'); 

If end is equal to start, I expect to get 1 block instead of error.

It seems like it's a bug. We'll fix it in the next version. Currently, you can request 2 blocks and use only one of them.

fixed in TronWeb 5.3.1
