Add a use-case as an example

What do you think about put all layout kwargs to some default config to have an ability to change them?

Do we really can use system encoding?

This PR adds a number of utils to perform interactive selection and validation of trace header specs:
TraceHeaderSpecSelector- a base class that defines a widget which allows specifying custom start bytes, dtypes and endiannesses of trace headers and displays loaded values for a subset of traces. It also prints textual headers of the file since they usually contain information about headers' locations.select_pre_stack_header_specsandselect_post_stack_header_specs- thin wrappers aroundTraceHeaderSpecSelectorwith predefined sets of headers to validate for pre-stack and post-stack SEG-Y files respectively.The resulting header specs can be accessed via
headersattribute of the returned object:Other changes:
