What version of Go are you using (go version)?

$ go version
devel

Does this issue reproduce with the latest release?

yes

What did you do?

Window_Size should have the same value range as Frame_Content_Size, when Frame_Content_Size exceeds the maximum value of int64, it will cause Window_Size to become negative.
According to RFC 8878, Frame_Content_Size can be any value from 1 to 2^64-1 bytes (16 EB).

Testing with the following values will trigger this issue, resulting in a panic

go test fuzz v1
[]byte("(\xb5/\xfd\xe40000000\xfa20\x000")

This change fixes an edge case in the zstd decompressor where
an int conversion could result in a negative window size.
