Issue in common.py

[ehsanmeisami]

When I run the read_next_block() with a .dat file from my bitcoin core folder. An error pops up. Code ran:

path = 'pybit/Blocks/'
f = 'blk02944.dat'
dat = Dat(path, f,
          verb=1)


# Read the block
dat.read_next_block()

TypeError:

I observe the same issue with different blocks. In my case problem lies in read_var() function, which returns an astronomically high value for pkScriptLen in read_out method for TxOut class.

I'm encountering the same issue. Has anyone made any improvements to the code to resolve this problem?
