291a29af1e *: do not use WriteArray for frequently used items 
`WriteArray` involves reflection, it makes sense to optimize
serialization of transactions and application logs which are serialized
constantly. Adding case in a type switch in `WriteArray` is not an
option because we don't want new dependencies for `io` package.

d2732a71d8 transaction: don't overwrite error and witnesses length check 
ReadArray() can return some error and we shouldn't overwrite it. At the same
time limiting ReadArray() to the number of Signers can make it return wrong
error if the number of witnesses actually is bigger than the number of
signers, so use MaxAttributes.

120ae4841f transactions: fix JSON unmarshalling of fees 
Fixed8 is already marshalled as a string and stripping quotes from it just
leads to interpreting it as a float with all regular float problems (like
test transaction failing with `txid doesn't match transaction hash`).
