Byte array search shouldn't need to specify length

[cromachina]

Describe the bug

You can enter a string of bytes for a byte array, but you also must specify the size in bytes.
The length should automatically be inferred by the bytes written.

To Reproduce
Steps to reproduce the behavior:

1. Open the app
2. Attach to a process
3. Select the value type: Byte Array (Hex)
4. Write a sequence of bytes into the Value field, like 00 11 22 AA BB CC
5. The default length filled out is 4 bytes
6. Click 'First scan'

Observe an error that says "ValueError: byte string too long"

Expected behavior
Length should be ignored or disabled when byte string is selected, and clicking "first scan" should just work.
The value type for "String (UTF-8)" seems to already work like this.
