[feature] ~/.upbit/credentials

[seunggabi]

Is your feature request related to a problem? Please describe. I want to use multiple user in get credentials in home directory.

# ~/.upbit/credentials
[default]
access_key = 
secret_key = 

[profile-a]
access_key = 
secret_key = 

[profile-b]
access_key = 
secret_key = 
...

Describe the solution you'd like

• as-is

  
  from upbit.client import Upbit

access_key = "Your Access Key" secret_key = "Your Secret Key"

client = Upbit(access_key, secret_key) api_keys = client.APIKey.APIKey_info() print(api_keys['result'])

- to-be

from upbit.client import Upbit

client = Upbit() # default client = Upbit(profile="profile-a") api_keys = client.APIKey.APIKey_info() print(api_keys['result'])

**Additional context**
I will make pr.
